Build an e-commerce wordpress site

I am on the hunt for a website developer to build a wordpress site for my new business venture. It will need to be an e-commerce site with the capability of buying products from me online. I have a domain name, host, logo, colour theme, fonts, photos and content. I'd like to then be able to manage the site on my own so it will need to be easy to edit etc.

I really don't have much budget so am looking for the cheapest possible option for this :)

Thanks!
