Devesion - Professional Software Development

My professional career is turning constantly towards my own software house. It was my goal since I started dealing with software development - is it good? I think so, there are a lot of advantages - flexibility, ability to making own decisions, working remotely etc. Two years ago I founded Devesion - small software house offering professional software development services, strongly interested in distributed systems and cloud computing. It was a great movement but as all beginnings are difficult I had to support with stationary, part-time job. Now I would like to switch totally into my own business but there is one small problem - how to acquire great clients to cooperate? Have you got any hints how to get leads ? Maybe you are interested in cooperation when it comes to professional sofware development ? Just contact me, it will be a pleasure to make business together.
