@roger,
Some of the reviews about them have been complaints about their proprietery software not working right the majority of the time, being unresponsive to their contractors, slow in paying contractors and a few other types of complaints. Other reviews can't sing their praises high enough.
The Better Business Bureau of Florida gives them a rating of A+, however there have been 88 complaints filed with the BBB against them in the last 3 years. There are no specific details on the BBB site, but I've been able to get a good idea of what the complaints were about by reading reviews on other sites.
Complaint Type Total Closed Complaints
Advertising / Sales Issues...........................40
Billing / Collection Issues............................3
Delivery Issues........................................1
Problems with Product / Service...................44
Guarantee / Warranty Issues........................0
Total Closed Complaints............................88
I'm going to look into working for one of their subcontractors for a month or two so I can see what is really going on before I plunge into it myself. I'll have to pay the subcontractor a set fee each month, but it will be worth it if it turns out to be not as it was represented.
