Tiling of a new bathroom - Tiling job in Edinburgh

I am unable to complete my loft conversation due to ill health; this is first job I require to be done.

Tiling three walls on new loft conversion bathroom, walls are new and sealed and square, with a coat of PVA on top. All skirting and architrave is in place.

No wall preparation will be necessary; all plumbing is already in place behind walls. I already have a number of tubs of tile adhesive.

Only holes in tiles are, mirror cable and one for cold water feed toilet.

Tiles are large high quality Colorker 610mm x 310mm and a band of mosaic ones behind shower mixer.

I have calculated it will require 53 large tiles with 5 spare, and have two boxes of mosaic tiles on mesh for behind shower mixer.

Wall 1, slopping 175cm wide, 220cm highest, and 155cm lowest
Wall 2, including full size doorway, 170cm wide, 220cm high
Wall 3, shower and WC wall, 270 wide, 220cm highest, and 70cm lowest

I will pay cash, but will require a high standard of workmanship.
