I put in a pool last year without a screen . Now it looks like a screen will be necessary to get full enjoyment/use out of the pool.

Can anyone tell me how much I should expect to pay for a screen enclosure?
My pool is free form (18 x 39) with raised spa and located about 20 ft from the house with a paver deck. This means I'll need around a 50 x 50 foot screen with foundation.

Also any advise (materials, do's/dont's, etc.) or names of good screen companies in the Orlando, Oviedo area would be appreciated.

Thanks,
Mike
