Marketing Software

I am in IT (Software technology) Recruiting / Marketing professionals. I need Employers contacts or new people in my business to enhance my contacts and business.

Can you tell me the web sites or people to reach in this IT (Information Technology) Recruiting and Marketing employers?

I’m marketing offshore custom software development and want to find out how companies really find vendors and how we can more effectively be found, at the time when companies are looking for our services, so that we can help them without bothering them when they don’t need the services. I want to be able to get us in front of the companies that are actually looking for what we do, so that we can help them. Also, we don’t want to pester companies that don’t need our services (or don’t need them right now). This will help us be more helpful to those companies that are looking for our services, without wasting the effort or expense of contacting other companies who aren’t ready or don’t need our services.

Open source software has a relatively small market share percentage when compared to proprietary alternatives (those created and owned by companies such as Microsoft). Since open source software is free, why more people don’t use them?
