Aggregate internet job boards like JuJu.com are the best place to find web development jobs.
Indeed.com is also good for searching for contract or full-time positions. It is a great aggregator of open positions from all over the web.
Dice.com is a great site for searching for IT focused positions. At the very least you should submit your resume and profile to their site.
You should also submit your resume to Monster, CareerBuilder, and any other big job boards. They may not have many good web development positions, but recruiters use them to find potential employees.
Another technique is to do a Google search for IT recruiting firms in your area. Then go to each of their web sites and submit your resume. They will contact you if you match any open jobs they are recruiting for.
