T-shirt e-shop

I am currently developing my database in Excel which will contain over 10,000 designs and other products listed on my site above. I know i may need additional IDs added to my database that i will be developing along side you, my future shopping cart programmer:) Currently i understand my website is unique cuz we are passing some very unique variables to the shopping cart listed above which needs to be programmed accordantly. I'm looking for a company that can help bring there skills to my template here <[login to view URL] _01> [login to view URL] 01 Help me design a unique, easy to use site. While at the same time help me plan the rest of my site which will need to be looked at after the first phase is complete. Thus far, i have started a bit on the customization process but I'm sure you will have other ideas to bring to the site that will help the end user with ease of navigation. I am open for suggestions for everything. I like how it is set up thus far but if you have a better idea, i would love to hear about it. Step 1- customer chooses there design Step 2- customer chooses there T-Shirt style Step 3- customer selects t-shirt color - design location - Shirt size - quantities(which needs to be updated on the template) - offer suggestions or requests If you have any ideas to add to help make the ordering process easer please add I have approx 10,000 designs and that number will continue to grow. The design pics are of all sizes, so the pics will have to be controlled with php to keep them a certain size. Also, the 10,000 designs in 3 different folders and inside those folders they are broken down in to other sub folders so that we can use the menu on that template for ease of navigation. Also each pic is labeled with a name for ease of search which will need to be configured If you look at the site, there is 3 steps labeled and the 4th step will be the shopping cart phase so i would some type of progress bar for the customer to see there progress. Lastly, i would like the customer to be able to upload their own designs somewhere in the steps so that we can continue to add designs, including custom orders.
