You need to figure out what you are worth and what your time is worth. Then figure out how long all of this will take you.
What is your rate for travel? You’ll be traveling 8 hours round trip.
What is your shooting package rate?
How long will all of the editing take you?
I can’t tell you what to charge, but figure out your hourly rate for editing and your day rate (up to 10 hours for shooting. Your travel day rate should be less than your shooting day rate.
Alot depends on your experience as a shooter and editor.
The second part makes no sense to me. Are you talking about time frames because YOU have relatives coming over? That doesn’t concern your client. If you can’t do it then don’t.
Also, if I were you, I’d draft a contract with payment terms and have them sign it. I would get at least 60% up front, and not turn over any DVDs until you are paid in full.
