Online Business Directory Script Or Yellow Pages Script

Hi There, I am Looking for Getting a Online Business Directory Script Or Yellow Pages Script to be developed or a ready available script installed on my web server. I prefer it to be based on PHP MYSQL. I have my own domain name and server space. I need the Online Business Directory Script to be something like ( www dot bizhwy dot com) But it has to be developed for entire Canada and states and cities within WITH tons of categories sub categories. Should look real professional. Should have options for paid listing and free listings. For posting a business with a link to web site and without a web site.. and you know check the web site . Should be able to incorporate Google adsense. should also be SEO friendly If you have something better than that ready to be just installed and configured then show me, if it suites my needs we make deal and you can install it.
