letting agent owners - help?

[Claire Bear]

my father has set up a letting agent, he has been letting for over 25 years. i have worked in a big name agent for a while and decided to leave to make a go of things.. we offer guaranteed rent scheme but we are struggling to get landlords.. can anyone recommend ways in which we can get our name out there? We thought it would work well, however the office seems to be costing us too much money and theres only so long before you run out!! We have trailor advertising, internet/social networking advertising and our local property paper.... We are based in Blackpool, Lancashire.
