Ideas on where I can advertise

[LMW1990]

Hi All

I audio transcribe for various clients and through those clients I end up typing a lot of academic interviews, dissertation/ thesis studies, focus and research groups for universities.

I'd like to start approaching clients directly (obviously not poaching my current clients customers!). So students, researchers, lecturers etc.

I also proofread coursework, disserations etc. I end up taking quite a few advanced bookings got these, especially for students whose first language is not English.

Where would be best to advertise my services?

Has anyone used such a service and if so where did you look?

TIA
