You'd really want to call up several local companies and introduce your business and skill set to them. If they don't know about you and your services, your odds of them ever contacting you is little to none. You need to make an excellent first impression, take them to lunch (or cater it in), showcase past projects and the fact that you have designated teams to handle .NET or PHP, etc. Tell them about your work flow (do you use SCRUM, AGILE, Waterfall), etc.
Sell them on the fact that you can help make their time more efficient by working in collaboration with their team or working on a separate project because their team is currently pre-occupied with a different one (so they can get two projects out instead of just one by year-end). That is how you'll land bigger projects.
