Build an Online Store

I have a retail business that is in desperate need of a website. I have the basics of a Magento site, so hopefully that saves some time on the products. Our business sells a line of specialty paint and vintage furniture. The website needs to include the following: - Woo Commerce (primarily for paint line products - about 120 skus) - A way to easily add photos of furniture pieces in the store and have these listed as products (for sale 1 time only because each piece is custom) - An event module. We host about 5 furniture painting classes per month - Social integration (Pinterest, Facebook, Twitter) - Maybe a blog?? I'm really undecided. - I'd also like a custom extension that can change the color of a piece of furniture in a picture to one of the paint colors we carry I need to get this going right away. My first developer left me stranded and it has been too long.
