website development

We have a client who needs the following 2 websites. We will do the design. Please only quote if you have similar script or did similar job in the past. Project 1: The project will consist of a site with an online shop where users can upload their image for printing on a shirt/beer mat/towel etc and will take payments via a hosted payment gateway. e.g. Worldpay. The site will have basic info - i.e. who, where, what - and will have a shopping cart for the products on offer. E.G. The beer mats site will have a list of beer mats that people can buy. They must be able to have the facility to design the beer mats - for example: - Quantity - Shape - Colour - Design (with ability to upload a design) ... and so on. If they aren't able to specify exact design requirements using the catalogue, they need the facility to send through a little online form with their specific requirements. All payment processing etc needs to go through the site, and all catalogue information needs to be held in one location. The project will need a full admin management system to be able to manage all features like products, customers, orders, categories, images, catalogue etc. Can you provide a cost and timescale quote for: - Developing the first site, including connection to the payment gateway - Cost to create additional duplicates of this site on an as-needed basis ( there may be 10 more this year) Project 2: This is for a greeting card site. The user would register and add names, addresses and important dates to the site - i.e. birthdays, anniversaries etc. They could then purchase cards for each "name". The cards would be real cards and the user would be able to do things like: - choose a design (from a catalogue) or add their own - i.e. upload a file - choose paper type - choose paper colour - choose envelope - add a message - specify when they want the card to arrive - i.e. on birthday, anniversary, other And so on. There would also need to be another part of the system where designs could be submitted by designers to the catalogue. They would need to be able to register and upload images. The administrator would need to be able to accept/ decline the upload. Each design sold may be paid a royalty fee, so the system would need to track how many times something was bought, calculate commission owed, and allow the administrator to say when something was paid. The designer would also need to be able to log in, see their sales and how much they are owed etc. Customers will need to be able to pay online via a payment gateway like WorldPay Please provide a cost and timescale for developing this.
