I hope you don't mind my being blunt, but it is unlikely you will be able to create the system you are seeking to implement.

This is quite akin to saying, "I need a vehicle that does what the Chevy Cavalier does," and expecting to purchase a low-cost kit that can let you assemble the car and be on the road with few skills or experience.

There are some open source (and free) software solutions that could probably be adapted to what you need, but you'll need some programming skill to do that. And hiring someone to adapt an existing tool is likely to cost the same as simply hiring someone to build what you need from the ground up.

It might be worth your company's time and money to invest in a website that can do what you want it to. Developing web applications is not suited to everyone. Building a simple web page is easy, especially with WYSIWYG tools. But, in comparison, you're talking about a plastic model of a Chevy Cavalier versus a real, working car with an engine and all the parts that make the vehicle usable.

If you hire someone who has the experience and tools, you could make the entire process quite painless, accomplish exactly what you need, and be able to maintain the contents of the site yourself, without having to know much (or any) HTML. And it will probably not be terribly expensive, depending on your requirements.

For example, I could build a basic database-driven system that could achieve the basic goals you stated for around $2,500, not including the design itself.

yes, something like this should be done in php/mysql, plain html won't do it, sorry. google won't work either, if you have a database and you want people to be able to search it on your website, you'll need to hire a programmer to code a search engine for you. if you're looking to hire someone i'd be happy to do it, as would many others i'm sure. just look around til you find someone your comfortable with.
