hi, i do loads for letting agents. they tend not to be to worred about cost as the money is taken out of the last tenants depoist. it can be a hasle getting keys and for you portable people ,power. i have found that getting the job done as soon as possible and never messing the agent around has kept them coming back to me. there is quiet often a small window in which there work needs doing and if you can keep getting it done then they'll use you. don't use letters, go to there office say hi and hand them some cards and hope that who they are using is a twit. good luck .
