Michelle,
Welcome to the forum.
If you read the
posting rules for the forum, you will see that we are not to mention names of contractors or HOAs. Typically, when someone wants specifics like that they provide an e-mail (which you can set up from any free e-mail service) for others to contact them.
Have you written a request for a proposal (which is basically what you expect the contractor to do) and sent it to various companies? I suspect that you may need two contractors vs. one. This is because the contractor who takes care of the pool needs specific training.
Another option is to hire an employee to handle those tasks. However, you will need to pay employer taxes in addition to any salary.
