Require a Shopify developer to build my online sales and business site

I have been in the art business for 2 years. I have a gallery and would like to grow my business by developing a strong business network via online art sales. The website I require will have the following objectives: 1. Sell art online. 2. Use the website to attract clients and partners. 3. Use the website to consult with clients and partners who are looking for art for their homes / offices / public spaces / projects, i.e. put together a portfolio of art works that would be potentially interesting for them to focus on. 4. Use the website as a brand building tool to grow our reputation in the art world, to attract the best artists, and to attract art investors. 5. Ideally, it will also be possible to use the website as an asset register for clients and partners to keep track of their art, i.e. what they have, where each piece is, who owns it (in the case of consignment stock), what it is worth.
