Database Web Tools

I have designed a relational database for what is, in effect, an online contracting system; consisting of individuals for hire (with associated skills and work experience), clients that hire them and the agents that manage them. I need this database to be manipulated with a set of tools, in PHP, PERL or ASP and anticipate it being hosted on a MySQL server. The tools should include a flexible way of displaying information such as skills, availability and previous work, so a relatively non-techie web designer could created a unique site that displays them. The backend maintenance of the database can be uniform in its presentation. I have create a set of functional requirements as well. The whole set-up is definitely not Rocket Science though, i.e. it is a relatively simple relational database doing nothing very clever. This project is, essentially, purely backend and will require no front end design ability, other than an appreciation of design issues for a designer using the data extraction tools. Any experience of Filemaker Pro could also be definite advantage, but not essential. Please send examples of previous work and very brief synopsis of how you would tackle this and how much you would anticipate charging, although I appreciate this is a slightly vague outline.
