How do you guys bid for a job. this is my first year at bidding my boss usually handles it. I plan on breaking down one of commercial mowing jobs that has trees, hills, fence, driveways and so forth. Then I will mark how long it take and measure the square feet of the area. Then measure an obstacles and subtract the area and see the difference in time for the areas and compare them to the jobs that we bid. So for example if we bid an entrance way and measure a hill with 10,000 square feet with no obstacles and compare that to a hill we mow that is 5,000 square feet for x amount of time we then take that time and multiply it by 2 to get that for the 10,000 bid. Then continue on doing this for each section and then add up for a total. Does this make sense and will it work or do you guys have a better idea.
