Welcome, Ryan, and it was good talking with you yesterday! I'm sure you know a lot of this, but I'll share everything I've found to be important:
1) Establish consistency in your networking. Since the industry is very tight-knit, there are situations where it is hard to break in, but I've found that is often due to people not wanting to take the time getting to know someone if they are just going to go to one meeting and then never come back. So I've found it important to consistently go to networking events so they start to see you as a "regular" and worth getting to know.
2) Make friends with other suppliers. They already have a client list and can help you break in and make introductions.
3) On this site in particular, I think I remember hearing that you were thinking about blogging. Well, I would also take the time to comment on other people's blogs and participate here in the discussion area. That shows people that you are wanting to be a part of the community as a whole.
