BigCommerce/Shopify E-commerce Website

Hello, We are a small start up that are going to be dealing with mainly some Islamic 'pieces'. We are new to e-commerce and so are looking for a detail oriented/experienced partner to bring our store to life. Ofcourse these sites do most of the work for you (and thus our choice). We will ofcourse need some design work, some coding, image optimization and so on. However, we will provide all the written content, the logos, the pictures, and so on. Thus, in our estimate it's a simple job for those with experience. Cost ofcourse is an issue, however, we would be willing to be a bit flexible with our budget for the right partner. Please answer the following questions : 1. Do you have experience with any of the above platforms? If yes, please provide examples of the websites that you've already done. 2. What will you be offering for your bid? In terms of concepts, work and so on? 3. Will you be offering any SEO? If yes, please give details. Lots of more questions, after seeing the bids that we receive. Thanks. Sam.
