We are looking to install a roughly 10×20 in ground pool in our side yard which has a slight grade change, but would still require a fair amount of excavation and possibly a few small trees to be removed. Looking at the options, could you provide a rough cost for a fiberglass pool? And would you do the project start to finish or do we need to hire a company to do the grading work separately? We are in the early stages and trying to see how reasonable this project is before getting into details.
