I think I have a solution for you: you need a spreadsheet program like Excel. That way you can educate your client on the real cost of producing a shoot like this in column A – and in columns B, C, and D you can give him/her alternative solutions to get ‘er done that may fit into their meager budget. And based on your description it does seem meager for such a big undertaking. One caveat – you may lose the job – BUT you will retain your sanity and you will more than likely give your client a needed reality check in the world of video production/ editing – a world that is ALIEN and archaic to most normal people.
Take hold of the reigns brother. Steer the ship. Educate your client!!!
Just wanted to say that this year alone I have successfully media managed over 5 large projects with amazing success thanks to these fine folks here at the cow!!! Now that is saying something.
