Volusion - File Upload Facility

Hello, We are a small UK company specialising in workwear garment decoration (embroidered logos, screenprinting etc), and are looking a for a file upload feature on our Volusion store so that clients can upload their logo/artwork during the order process, rarther than send it via email. We are also looking for a multiple colour/size option feature, where clients can choose various quantities of the same product at the same time. We would need the various colour options on the left hand side and the size options along the top. The client can then choose the colour/quantities they need - e.g Polo shirt - Green - 5 large, 4 medium, 3 small etc and add them to the cart at the same time. Examples of yourprevious Volusion work/projects would be desireable. We are also looking for a site makeover at the later date, subject to finding an excellent Volusion designer we can work with on a regular basis.
