I am needing to get a bid together for a small town. the lot has two baseball diamonds and the rest of the park. there is enough there to fit 5 ball diamonds. just a few pieces of playground equipment and minamul trees. then there is a small building a single tennis court and small swimmng pool. they want it edge and trimed. How should I go about figuring this., the bid will also include another small park and city building. I can figure those but not sure how to do the large one any help would be great.
