78545 Movie Rental Site

Here is what I am tring to do: - start an online rental website website where my visitors can come and rent a video from me and I mail it to them. It going to be alot like [login to view URL] in a way. I will need a way that I can add new movies every week, update the website when movies are rented out, and be able to take peoples credit card numbers for the membership each month. If you think you would be able to make a website like [login to view URL] please get back to me with a price. I would like the script to take new members payments and give them a user name and password. Anything else you think I should add to the website to make it work better I am willing to listen.
