You guys know how I feel about that thousand per finished minute ballpark estimate being wildly inaccurate. But to the issues:
For the shoot, you bill a day rate plus whatever it costs you to get there. If you have to rent a car, charge for that. If you use your own car, about 25 cets per mile is the last figure I recall charging. You bill from the time you leave the driveway, what’s called “portal to portal”. Track the miles driven to the shoot and double it to account for the return trip. You can choose whether you bill a lower hourly rate for the driving versus actual on-location time.
As to the DVD’s, what you’re really doing here if you’re smart is editing four sets of clips into one nice video, then taking that program and chopping it into segments, then customizing the titles to fit. You likely have a lot of shared assets between the four pieces, (graphics and music wise) so it’s not like you’re doing each one completely from scratch, more like working to a template. If you make the master program in this fashion, what remains is to break-out the segments and drag-drop each of these into the DVD authoring program and adding the apropriate menus and rendering it all out. Not a huge deal, so treat ths as a single editing job and bill at your hourly editing rate. Figure eight hours travel toal, two hours to shoot, six to edit, another three to author, maybe you don’t charge for rendering time unless you are sitting there babysitting it. With those time estimates times your rate, you have a ballpark figure, ask for one third of that amount up-front, the rest on approval of the master. When you give them an approval copy, put a watermark like a time-code window or your logo over a portion of it so it can’t be used as-is, only evaluated. This prevents them using it before thye pay you to give them a clean copy.
Don’t know what your rate is?
Short version: if this is what you do for a living, total up all your costs for the year: utilities, expenses, insurance, gear, software, maintenance, expendables, etc. Add an amount you want to put away in savings towards more or better gear. Total that figure. Divide it into 350-some working days (leave out vacations). From this you get a daily amount you need to be bringing in just to BREAK EVEN. Next add a mark-up for your actual PROFIT. Compare this figure to others in your area, try to keep yours near the middle range of those rates. Now, you know what you need to be charging per day and per hour.
I’m going to an awesome indoor RC plane event this weekend in Champaign, Illinois. Check out the e-fest (google search).
