I gave a bid today for a small lawn 10- 12000 sq. ft. no obstacles at all just mowing edging and trimming. I quoted a price of $45. The customer says wow you are way lower than the other 2 estimates I have. Should I have quoted a higher price seeing that there was a Lexus and a Cadillac in the drive way? It always makes me mad when I feel like I left money on the table.
