An online store for canvas printing & picture frame

EDITED on 9/8/14: I need a e-commerce website selling picture frame and canvas printing. We are not normal re-seller, we are the factory. We produce the products and sell to : re-sellers and end users Our requirement (might add on..) : - UI to be simplest possible. I love Apple website a lot. We do not want anything that is too responsive where a lot of flash/images moving here and there and colors change here and there. Keep it simple. - The users of this website: Super Admin (me) Admin (re-seller) Designer (designer who work with us by supplying us the artwork) End users (public customers) - Knowing who are the users of the website, you as designer must built the web that work for them. For example, the website must able to keep track the designers artwork selling records. We need to share part of the profit with them by supplying us the artwork. Another example, once re-seller log in, the price shown should be lower than end users. Another example, if re-seller is to place order in front of the end user, he can choose to key in the login name and password while sending order to us, so the price will not be shown to end user. YOU have to built the process of the system. We will judge and discuss further. - We expected international business. So must able to plug in DHL, FEDEX...delivery calculator. - There should be a way for customer to upload own image, crop image, select frame, and wait for our team to have a look. Then client need to approve or instruct for changes. (example : "[login to view URL]" ...watch the video in the landing page) - For image cropping module, we currently have it in php. (refer to [login to view URL]) - You have to study my web hosting spec: [login to view URL] Do not build something that can not operate in my web hosting environment. At the same time, we hope to hear opinions from experience developer. TQ.
