Chances are extremely high that the Paul Davis, Servpro's, and Service Master's, etc. in your area do program work and are not independent.If I was in your position, I'd hire 2 independent firms who are certified by the IICRC in Fire & Smoke Restoration (FSRT certification) but ideally, have a Master Fire & Smoke Restoration certification.

There seems to be a lot of them and I guess I'm looking for one that is reliable, easy to work with and charges relatively low fees. 

How many units do they own (I like a low amount)?

Ie If we got the property, the price is low enough that my wife and I could personally cash flow the building until it was stable, but is that a 12 month time horizon?  

For all we (forum readers) know it was priced artificially low to inspire above-ask bids.

Everyone is extremely helpful.

The thing is, I make very low money per hour and I can't go on like this.

So you sell it low so the offers received are even lower.

I saw your ad for the (name something descriptive from the ad) little blue bunaglow and I'm extremely interest.

It takes a good bit of tenacity for surenarrow what market you want to invest in, start building relationships with people on the ground (realtor, lender, property manager, contractors), learn the market extremely thoroughly, then start bidding.
