I have a good amount of knowledge in PHP scripting. I also have excellent knowledge in Web Designing, although I am not very creative, I can do any form of styling you need. Check out my Portfolio for examples of what I can do.
I will be honest, I've yet to create a web store, but I definitely have the knowledge and persistence to create an excellent one. If you are considering me, please message me so we can discuss what your site would look like and what you need from it.
Depending on what exactly you want, I could do this for you for only $90.
