I gotta call from and elderly couple today about a warehouse wich they own. i went to see it earlier.They want someone to remove all the dirt wich has accumalated on the floor. its a decent layer of dirt wich was left to build up for about 6 years. They also want a moderate amount of trash thrown out. It was formerly a diesel repair shop. The building consists of three shop areas about 1000sq feet or soeach which i thing you could fit two 18 wheelers in each shop three office type rooms and a parts room wich isnt that bad, just needs trash removed. The trash consists of several small oil drums wich are scatered everywhere. And lots of small oil containers and various shop related refuse. I calculated that i can do the job in about 8 hours with the help of three other laborers whom i pay 10 an hour. I bid the job at 450 and called them earlier and they said they would get back to me tommarrow. They are planning to sell the property and are trying to tidy up for the new owners. Was this too much to charge, if so what should i charge?
