Did a job recently (for a builder) with same size mosaic but ceramic, kitchen splashback about 2.5m2 in total with 5 or 6 sockets. Billed £250 plus extra for edge trim and grout for job and was paid without query. Then again, I'm in a different area to you.
I'm doing a travertine mosaic at the moment. Its the first time I've done it and I seriously underestimated the time involved in doing it. I was supposed to finish today but I reckon I will be another two days.
22 sq m travertine mosaic on the wall and 11 sq m porcelain 300 x 300 on the floor. I quoted £1400 for it so even with the extra two days I'm still quite happy.
Today was my seventh day. 12 hour days. I'm knackered. I reckon I'm looking at Friday evening or Saturday morning finish. There is hardly anywhere where I have been able to put up a full sheet. Its been all cuts and buttering up the tiles.
The lady waited three weeks for me to start the job so I told her I would work through to get it done quicker for her. Boy am I regretting that now:wilted_rose:
