We would be happy to help if you are interested. My strongest advice would be to stick with a reputable company and not someone who pm's you and says she can do it for half the price because she can't.
Best I can tell you is do your homework and do what you think is right. Both companies in this thread have good build lists. Make sure you look at these when comparing units and price. If you would like to discuss some other options feel free to give me a call when you have time. 1-630-595-9770 Best of luck. Vince
