Patio restoration

Wanted to have my patio power washed to remove old sand that is coming out, have new polymeric sand put in between pavers and then have it re-sealed. Patio is in the back of the house and looking for free estimate to have this re-done, was done just a year ago and was not properly sealed and most the sand is coming out. Possibly would like an estimate also on having the driveway and sidewalk cracks sealed. Also an estimate on having the windows cleaned on the exterior portion. ***Patio is number 1 priority.
