I need to give an estimate tomorrow.?

Question

Im not sure about the dimensions this is what i remember as for now well anyway

How much should I charge to cleanup an 80x40 backyard full of large weeds and lots of dog p**p? What is a fair price to charge. In my posting i mentioned i charge 10/hr depending on size and condition since i said that can i charge just a flat rate. Or is that messed up on my part. In my ad i also mentioned that you must supply the materials, but in this case i have to use my own. Please answer this as if you were the paying customer. Thanks so much for your consideration to read

Answer 1

Figure out how long it will take you to clean a one square foot area.   80' x 40' is 356 sq feet.  Then multiply how much you can clean in one square foot by the total (356).  Then you have your bid.  You can use this formula for any of your jobs.  

Total # of sqare feet times what you charge per sqare foot.
