Web site creation, php, mysql

Hi, I need both a website and a business image, I may list the graphic design separately if required. The website will utilise database results to provide the information in each category. I want a site which appears and functions similar to [login to view URL] What I have and what I need. 1. I have a spreadsheet with a lot data on it. I need to be able query the data and have the small amount of results posted accordingly. (the results should only change occasionally, about once a month) 2. I need to be able to add/remove criteria to the spreadsheet/database. And I need the ability to choose which of the data from the spreadsheet is viewable online. 3. I need to be able to modify the formulas within the database 4. I want the database to be able to be added to from a registered account (after admin approval) Feature for manufacturer to supply appliance details and images through a form which suite the database requirements Have a look at [login to view URL] and you'll get the idea. I have attached an example spreadsheet. You can see the queries that would have to be run to get the results. You can see that there is a lot of data there and most of it is now not needed but we want if for future purposes so the database is always expanding. Maybe the queries could be stored and run locally, only posting the results to limited upload slots within each category on the server. So you need to be able to sort out the query side of the process in order to retrieve the results. Shouldn't be a problem if this is your area. I am open to suggestions as to outsourcing separate components of job if you have any suggestions let me know. Please supply example of your work when applying. I am happy to agree to milstone payments.
