The only negative thing I have to comment is around the fee that First Tutors charge which can be between £4.99 and £24.99. I recently used a chemistry tutor paying £24.99 to release her details. Then paid the tutor. I also wanted a maths tutor which would have cost another £24.99. I found a maths tutor elsewhere. I was told by First Tutor that this fee which strangely ranges in price, is to cover the cost of qualification / reference checks however I would hope that you would check all qualifications before adding a tutor to your site. There are many other tutor services that do not charge that fee and I am more likely to use an alternative company.
