Any real estate firm should have the info.

I have 20 years experience working in the IT field, and currently have a JOB doing just that, but some of that time I owned a consulting firm and actually got my real estate license and for 5 years listed REO properties and did some flips along the way. 

@Aaron Ramm I offer property management services in Everett through my brokerage firm Champions Real Estate Services.

I worked for a small firm in Constriction Engineering Products, Johnson Controls, that sold air and water control equipment to large apartment and commercial building contractors.

Needless to say I am completely sold and now slowly transitioning to dedicate to RE full time with an acquisition firm in South FL were I will be connecting investors with our acquisitions and gaining full knowledge on a daily basis. 

Then maybe just visiting firms near me.

Better to hold firm and tell them to file an insurance claim.

We have also used Steve Thomas from 5T construction who also is sharp but always seems to be about 10% more but his firm can be trusted.  

I'd start looking around at real estate/business law firms in your area and set up a few consultations. 

-----Edit to add (And this may spark a lively debate, which would be awesome)The link to 123flip above with the schedule for contractor payment works pretty well on small jobs (say, $35-40k or less)On large jobs, it's not very reasonable to expect a GC firm to carry 40% until the last nail is driven and 30% until the mid-point of a job.... unless they are charging you substantially for the carrying cost of their financing.
