it's only going to get worse. That's why I'm always harping about producer skills being more important than camera skills. Even 5-10 years ago before all this pro level equipment was affordable camera ops wern't making very much money, maybe 40k a year if you worked for a tv station or something. Making the phone calls and doing the legwork of setting up gigs is far more important than delivering a nice product, (and you get paid more than twice as much, even tho it sucks and is not as fun to make a deal vs. hit record) I bet the video will come out alright, not perfect, under lit, soft focus (like every dslr video). But the important thing is you're getting paid and can use it to build your portfolio and move onto other clients.
So OP, my main tip would be to cash the check ASAP, and in the contract outline exactly how much work they are paying for in hours. Or you will be making a thousand changes later for free. Oh, and for the love of god use a tripod. Also don't let them pressure you into using copyrighted music, you will get thrown under the bus if the record label comes knocking.
