Many thanks for all your help aiding my search for a suitable position on qualification. I just wanted to put in writing that I am extremely grateful for all the time and effort that you took in discussing with me my goals, ambitions, and requirements (and I know I am picky!) as well as my concerns, and am very pleased with the position that you have helped me to find.
In my search for a NQ position I approached one or two other recruitment agents (before approaching you), and unlike the other agents I have always felt that you have done your absolute best for me, and have been prepared to spend time and effort with me as if I was your only client (which I am sure is not true!).
