The order form .pdf's will have to be updated to allow spaces to be filled out, but other than that -and the fact that paypal takes a cut out of payments- I don't see any substantial problem.
The procedure- at least at this point- is this:
1) order submitted (via email)
2) order recieved, postage calculated, confirmation email sent
3) payment sent (via paypal)
4) payment recieved and compared to order
5) image is processed/printed/framed, ect.
6) product or file is mailed/emailed (in the case of photoshop work)
7) payment is transferred out of paypal
Seems reasonable enough. I'm doing the limeade video tonight. I learned a lot from making the last one, since the dialogue was recorded seperately. And the background music was a little too loud I think, but it was difficult to work the volume percentages. I may not actually actually make the video, but I'll get the clips for it and write the dialogue. I think I can work a bit of humor into it crushing the ice. I don't have the seltzer water, at least I dont think I do, so I'll use sprite instead, since it's an acceptible alternative.
I'm not sure how many instructional videos I'm going to do. I may get clips for making spaghetti from spaghetti squash tonight too, but this is just a side project. Unless it turns out these little videos are popular, in which case I can give it a higher priority.
