Tile and Grout Sealant

We need someone to lay down a protective sealant for our tile floor. Living room, dining room, bathrooms. 800 to 1000 sq feet. Preferably someone who has experience with this and is able to arrive with their own equipment and hopefully the appropriate protective sealant. Please email a quote and I will get right back to you. We are offering 300, but if that is not reasonable, please send a bid. This is first time for us. Thank you.
