Lift Tickets:
Seven days at Les 3 Vallées (~$450), the World's Largest Ski Resort is cheaper than a window rate of 1.5 days at Vail/Aspen/Park City or 2.5 days at Alta (which used to have one of the most affordable lift tickets Out West). I am sure some of your crew will have EPIC passes for seven free days.
Lodging:
Do you have a preference for a 3 Vallées base yet?
It does not matter too much. Meribel - more central, British/English, chalets & apts/fewer inns. Val Thorens - higher, snowsure, more international. Both have a Folie Deuce apres-ski bar. Wherever you find a good deal, most everything (90%+) will be ski-in/out or just a few minutes walk to the lift/slope.
Some things to consider:
There are some relatively new apartments in both locations. I stayed in one in Meribel (Mottaret) in January 2006. Again, they will be smaller than US condos.
And if you can find a chalet, that might be even better with meals/catering and accommodating larger groups, but I think they want mostly one week. (?)

Transportation:
There is so much terrain in the Tois Vallees; you do not need to take a day trip to another area unless you really want to experience Val d'Isere, Les Arcs or Ste. Foy (local powder favorite).
On my first trip to 3 Vallees and Val d'Isere/Tignes in 2006, I took the bus (I forget the name?) from Lyon Airport to/from ski resorts. On the same trip, my group rented a car from Lyon to La Grave (as well as Serre Chevalier and Les Deux Alpes when La Gave was closed).
Depending on what you want to do or visit, you might want to take the bus. The road up to Val Thorens from Moutiers/Valley is a bit treacherous, long, and narrow for the traffic it sees. A day trip to/from Val d'Isere will be nearly 2 hours each way despite being less than 60 miles away.
Ski Guides:
I did not use any when I skied Val Thorens/Les Menuires/Orelle/La Masse (Meribel & Courchevel closed) in April 2018, so I do not have any recent knowledge - or personal recommendations. However, I knew where I wanted to go, and the most popular freeride routes generally have a few tracks.
I recommend hiring a guide for at least two days, focusing on 1. Val Thorens/La Masse and 2. Courchevel/some Meribel. Possibly a third day if it snows to provide safety and how to avoid crowds. It's easy to justify with your own group, and the cost of lift tickets is low. In Val d'Isere/Tignes last year, we were able to cut lift lines as well. That is not always the case everywhere.
When in doubt, I often use the Local Guide Office - they will usually have the best rates. In the past 5+ years, I have used the following in other areas: Compagnie des Guides de Chamonix, Alpine Guides Society of Courmayeur, Guides de Verbier, Engelberg Mountain Guide (with Tony), etc. Val d’Isere and St Anton have English-speaking groups/outfits you can join.
I would try the local Meribel or Val Thorens Guide Offices, ESF Guides, or Oxygene (name-brand instruction/off-piste company for all the French majors). Things to watch for:
1. Max Group Size. It could be only 6 or up to 8. Verify. This will impact the $/day per person. If you get a harness out or crampons to access a couloir/belay, the group size will be 4.
2. Equipment. Determine whether they will provide you with an airbag and other gear (beacon, shovel, probe, etc). Most do, but sometimes it can be a surcharge. Unlike North American operations, they will let you use your own equipment if you want.
3. Credentials. Sometimes, ski instructors serve as guides but lack the IFMGA Mountain Guide credential. This means they cannot lead you over glaciers—I found this out when comparing guides/prices to ski The Backside of Mont Fort at Verbier.
4. Guides can meet you at your lodging or a specific lift. (For example, for the first tracks at Val d'Isere, starting at the Le Fornet sector can be necessary.)
Examples:
A very good deal: ESF Val Thorens - 440 Euros for up to 8 people.

Most seem to be around 600 Euros for a group.

Tipping: It's expected to pay for a guide's lunch daily and possibly an after-ski beer. My UK friends lectured me not to tip more - so I didn't around them. However, I would tip when a guide took me a run/itinerary I requested (individually or as a group), or found excellent conditions.
Scheduling: You might want to consider how many guiding days upfront. Guides can get booked up, and it's better to have often the same one who gets to know your group. It's not always easy to simply add days while you are there.
Heli-Skiing
It's not allowed in France. They can pick up/drop off groups in France, but you are skiing in Italy. Reading lightly, they will likely send you to the Aosta Valley - near La Thuile.

Guide Books / Off-Piste / Freeride
Unfortunately, few excellent guidebooks are available for the 3 Vallees. You might pick up what they have at a guide bureau.
Strava destroyed Fatmaps, which I would have recommended. They would have shown all the freeride routes and the ski lift/piste map. It's minimal now.
Here is a classic route:
