You can wash everything else with Odor ban or whatever other chemical out there promises to rid urine smell.

We have lots of people from out of town working at the chemical plants. 

Is anyone aware of a potent way to address the fleas and where to purchase the chemicals?

Specialized chemicals and pressure washing would be needed in my opinion.  

They also have chemicals and equipment to clean spots that the "rent from grocery store" systems can't touch.

It must be Food Grade or it's poisonous.It works better than chemical flea killers and is non toxic to people and pets.

Other days they are paying late,a storm rolls in with weather,and you get multiple calls for repairs at the same time,and oh yeah the tenant you thought was coming in they don't qualify for the check you run as you find out they were lying.As for the contractor.J Scott's situation is different in that the cost of living is way higher in New York than in Georgia.So a project manager getting 60k in New York you would pay is not the same as in Georgia.My brother in law got offered 25,000 more per year for a job in New Jersey to move from Georgia.After he factored in all the costs he was breaking even to losing money plus the weather was harsher up there affecting quality of life.I don't know if your flips up there would allow you to pay an amount comparable to what J Scott pays here.Interesting comparison here:http://www.bestplaces.net/col/?

Resurants, food preperations, chemical industries and probably oil and gas as well (considering the environmental impact issues).

I dont mow but own a chemical lawn care business.

Ok finally I can do this post I wanted to tackle it before but i ran into some issues with getting the floor together.Ok so you have a floor that is relatively in good condition but there are a couple of boards that are damaged beyond repairWhat could cause such a thing.heavy machinery being dragged across the floor. fire damage.water damage. chemical spillIf you don't have the time or the money to redo the entire floor but it is just a few boards that are out of whack there is a way to tackle this job without a lot of effort and time. you dont have to do the whole floor. most people will tell you it is impossible to match stain and this is true it is really really difficult but there is a trick that you can do. it is called monochromatic color effect ( i just made that name up but it works )you will need a fine cutting tool like a multi-maxa brush or a rag and three or four colors of stainyou will use the multi-max tool to cut along the seams where the boards meet each othercut down into the seam cutting loose the tongue of the adjacent boardstake your time. if you are cutting a length of board and stopping before the board is finished. then make sure you stagger your lines so that you get the staggered look floors are meant to have.you will need to find wood that is of the same size..
