Giving it a little thought ... not being a music industry insider but an avid fan with a little sense and having looked at the music landscape for many year
With the current demand of bands from the 80's
What you can reasonably expect from this undertaking

If 7x70 doesn't already have a recording contract in place it shouldn't be challenging to get them a record deal -
from my understanding the band usually makes 1.00 to 1.50 per unit sold (Check for yourself I could be wrong)

On name value alone, booking 7x70 on a North American club tour (local clubs - playing to 500 to 2,000 fand per night) should not be a problem - Obviously this gets them in front of their fans and gives more sales ops
Usual deal is flat fee and % of door or % of door

This is very similar to what many hair bands from the 80's are doing now (Vince Neil, LA Guns, Cinderella, Quiet Riot so on and so forth)

Merchandise from the bands is always available at these shows via a booth or table set up

The biggest challenge may be getting airplay - radio and or MTV or similar video outlets - that type exposure is what will help move 7x70 to the next level

Behind that with promotion (internet, radio, TV and live promos - like in store records signings and touring) reasonable sales expectations can be in the 100,000 to 400,000 record units sold - more if the band can get heavy airplay
Add T-shirt's, posters, other apparel and various sundries to items available for sale to fans

Internet marketing campaign combined with traditional marketing - get in front of as many eyeballs in all target markets as possible by all means available

Obviously please don't take this as gospel and as always due diligence

MikeW, KB/D$ and Sykk and a few others will be able to add and amend this
