Create a New Wordpress Theme based on other existing

I need a professional Wordpress designer able to design a new theme based on other existing. It´s a news magazine theme where you can add info about business (hotels, stores, restaurants, and whatever) Every potential customer must have the option to upload their own information, upload images, files, set address in google maps, add link to their website.... and they will be able to pay me via credit card or moneybooker. If you want, you can check the website... That is all I want.... Of course, you will have to import my existing mysqul... [login to view URL] Page where they can upload information [login to view URL] Website must be available for IE, Chrome, Mozilla and others.... I´d like to make some modifications in CSS Please, tell me about your experience and give me a budget. We will discuss more about the project when you visit my website and bid for it. thanks!!
