Wanting to go into commercial

I have 2 years experience working in both residential and commercial(a little more residential then commercial) and have decided that commercial HVAC-R is the career that I would like to pursue whether it be working with refrigeration(which i would prefer) or with A/C equipment. I'm EPA Univeral certified and graduated in May of 2008 from the HVAC program at A.T.I. in Dallas. I've always been more interested with commercial equipment and how it works and all the small components that make up the equipment and think it would be very rewarding for me if I had the knowledge people wish they had to be able to fix and work on them. I know it won't be easy and will have to start at an entry level but everyone has to start somewhere, it's just finding a company that is willing to hire you in at entry level that is the problem. I have worked a little with chillers and cooling towers and commercial equipment like it so I'm already familiar with how it all works so it's not like I'm coming into it not knowing anything about it. I am a hard worker and am always looking for an opportunity to learn in every way I can so that I can be more successful at what I do and can move up faster in positions. I am 22 years old and have a wife of 3 years and 2 little girls, one is 5 and the other is 2. Yes, i started life early but I would not trade it for the world because I would not be where I am in life if I hadn't.

If you or anyone you know is looking or is willing to hire me at the level I'm at then any help would be more then greatly appreciated!! Thanks
