Hello
I know my bid is out of range, but honestly, it's just for what you're telling in your description, an online store, no other details :) However, this is a placeholder bid, we'll discuss the price once we talk about all the details. Upfront ... I have an e-commerce platform of my own, built with PHP on top of Zend Framework with MySQL as the storage engine, I have several implementations into websites (I can show them, you can also see some in my profile). I'd like to hear from you more about what kind of products do you plan to sell, what filters do we need for the search and advanced search, what shipping and payment modules do you need and so many other details.
As far as the graphics part is concerned, since I'm not a graphician, I'd rather prefer you doing the design with some local graphician and send it over as layered PSD files. Most of my customers did this because they wanted to have the designer handy and to be able to talk to them and explain to them what they want their websites to look like without any language bareers. If you think you can't find one, I do have a couple of people I collaborate to, I can ask them to do it. Or we could try to find some nice template over the internet, there are tens of thousands of, really good quality many times, just need to pick carefully, then we can adjust it to your needs.
Lastly, since I'm registered as a company in my country, you will get invoices from me to use for accounting.
Regards,
Dragos
