There's nothing here that's particularly different from other kinds of work. Charge your hourly rate times the number of hours you spend on the project, rounded to the nearest tenth or quarter hour or whatever. If materials or travel are involved (like going to the location to reshoot the background), factor those in.
It's often hard to know how to set a price when you're starting out in a business, and it's natural to low-ball the price in order to please the customer. But think: if the customer says "That's great! At that price, I've got a hundred more that I'd like you to do!" would you be happy to do all that work at the same price? If not, your price is probably too low.
