"Rockband" game stems

I have done music for games before. But this is new to me. A client has asked to use one of their songs on the game "Rockband". Seems like straight forward stuff. I recall the mix and hardware settings then send the required stems out with a single start time. But will take a bit of time for recall due to using mostly hardware effects etc. And then the time to print a bunch of 44.1 tracks. And the time to burn safety copies. Seems like rockband itself charges $250 for this. Not really sure what to charge them but I told them it be better if we did more than one song. Any suggestions?

And also whoever did this before anything I should know?

Here are my instructions... http://llnw.101distribution.com/u/assets/build/10.06.26/pdf/rb_faq.pdf

Just wanna know if there any pitfalls in that game besides the -.5 db I should be aware of. And if anyone had any problems occur. I want to give them a good price and a perfect set of stems.

Thanks in advance,
John

And is this just a scam thing? I won't be able to contact the actual band members. Only the check signers...
