Looking to increase my sales.

Hi.

I am a cloud systems engineer and started a business on the side selling business phone systems. Owning a business has a lot of complexities but for me the problem it's sales. I am great at doing technical work but when it comes to people I hit the wall. Houston it's a big city and there is a high chance that I can be successful with my business if I do it in the right channels.

Houston business owners. What are the best ways to build client networks and advertise in the city?

Thanks in advance.
