New web site design and development

I need a website created. I will supply the logo. All other design work will need to be supplied by you. This site is for a water testing chemical supply company. The site will require php/mysql. The front page needs to be clean and eye catching. The front page will contain 2 short introductions (will be supplied). The core of the website will be the product line and how users view and search it. There are roughly 600 products (Please see attached excel spreadsheet). The products will take advantage of php/mysql. We would like the user to be able to sort the product range in several ways: - A list that displays all products - User to search on product type (see spreadsheet) - User to search on what they want to test for (see product description in spreadsheet. The description will tell you what the product tests for such as nitrate) - If the developer has any other ideas on how to sort/search the products list they will be considered as well The site will also contain datasheets (currently in pdf format and not supplied at the moment). The datasheets will need to be accessed through a search and a full listing. We would also like the datasheet to be linked to a product (see last column of spreadsheet. No data yet) …..eg when a user searches for a product there will be a link to the specified datasheet. We haven’t entered any data into the last column but would like this feature in case we decide to use it in the future. We would also like a backend feature that would allow us to delete, edit and add new products or datasheets when needed. We also require a simple product ordering feature. The user will be able to select the product they want to order. The order will then be emailed (no banking/credit/paypal facilities needed). Please PM me for more details. Thanks
