Job Search Engine (Crawler-Spider)

Looking for someone to develop and design a job search engine (crawler, spider) that can search by "key word' or "function" on company career sections of their web sites. Index the jobs and bring them back place them in a MySQL database and then format the jobs by job title, location, description, etc.

I am not looking for parser or search strings to each company web site. The job seeker must be able to search by job title, company, key words, and by city state or zip code.

In the admin panel --I must be able to populate the company URL's for the spider to be able to search. I need an unlimited URL database capability for the spider to be able to search from.

I will need the companies that are interested in completing and biding for this job to submit a test crawler or spider to prove you can do the job. You can place spider on a protected web site to protect your propriety work. This is a must. no exceptions. We have had to many companies, developers saying they can develop this spider and it does not work. Must need proof in advance.
------------------------------------------

The spider that is created must not violate or go to any unauthorized areas of the companies web sites. Must only be programmed to search the career sections of their web sites. Must function as an extension of the job seekers finger.
------------------------------------------

Test Web Site--Before bidding on Job you must be able to provide a test web site to demonstrate that you have the crawler or spider we are searching for. Once tested, and the spider meets ALL of our requirements, then we will pay for search engine in full. This ensures we are getting what we are paying for.
------------------------------------------

This project is for a company that already has the job search engine spider code created or has a similar source code and can make some small changes to their current search engine (code) to make our specific spider requirements. This will ensure quick turn around to post on a test site for us to view and to test the engine. We are looking for a quick turn around on this project.
------------------------------------------

The Spider will need to search by key words "job titles" such as : sales representative, sales manager, etc. We will provide to you a list of the job titles (keywords) the spider will search for. So you can program the spider to search by these pre programmed titles or key words.
