automatic picture/photo email with different background

I think there might be a program like this out there already. but this is what I want. I want people - Tourist visitor - to be able to take picture of themself and be place with the pre-select attraction background --> then able to email to themself. I would like to have a program that will let people take their picture with (white background). The program will have pre-select wall paper-- then it will automatically put the picture of the people that is taken place in the wall paper background. - automatic croppping. I want to do this at tourist attraction. Therefor, you will have to think of many people using it at the same time. EX: 300 tourists. The set up would consist of 3 camaras. There will be 3 computer screen that will let people select their picture from the main picture bucket. Let say I take my picture. I will then go to the computer screen to select my picture from the main picture bucket. This main picture bucket should have all of the picture that have been taken in the past 5 min. I then select my picture, it will pop up to a big picture screen. With this big picture screen, it should have an email- bar where I can just type in my email address. then it will automatically send it to me. If you are able to do this for me. I will pay you more to take it to the next step. -- build a website that will intergrate with this program.
