Build a website

We are a small non-profit and I'm looking for someone to build a website to sell a few products. I would like the site built on Shopify. I have the domain through GoDaddy. I need to be able to make updates and changes to the website after the design process is done, so it would be good to have the site built within Shopify so I don't have to mess with detailed coding. I can provide similar websites that we can use for ideas.

The site will start with about 12 pages.
I need a webpage with:
Home page
1 product category page
6 product pages
Our Story Page
Contact Page
Policies page

Time frame I would like to get this done quickly.

Please submit your bid and turn time.
