Sears, Home Depot, Lowes, ect.

Just wanting some input from some of you guys, My business is a new one, Started up in March of this year, and things are slowly building up but I have been thinking about going to Sears, Home Depot, Lowes, and ProBuilders about doing some subcontracting work. I have all the needed insurance and licensing, and the man power to do more jobs than I am doing currently.

Anyone have any prior experience as a sub with any of these companies? It seems I have read horror stories on this board in the past about getting your money and alot of hassle, ect ect.

I have also heard that service magic and other lead providers are a bust, any info or experience with them would be greatly appreciated.
