Math Problem...or Pronoun Trouble?

Ran across this ad on craigslist:

looking for a person to book shows worth while for this band by using this link http://www.southfest.com/tennessee.shtml

we are www.myspace.com/rustysharpthings

paid per gig booked. you get 90% of what we get paid. no joke. we get nothing you get nothing. we get a grand you get $100.

thanks.

Let's see...I get 90%...so if the band gets paid $1000...that means I get...$100. Hmm. That doesn't sound right. Dang, this music bidness is more complicated than I thought!

Oh, well, they sound great and have cool art; guess a person can't be expected to do everything well. I just hope whoever wrote this isn't the one counting the money after the shows.
