I have to tell you I managed to nip a flame war in the bud (mixed metaphors, sorry!) on the Harplist because I copied your request and posted it on the list and a couple of people got their feathers ruffled (another metaphor) because they thought you were being overly optimistic about learning the harp really quickly. Consequently, I didn't get any more replies apart from the offer of the small harp for sale. I do recognise a couple of Harplist member names from the above list, though.
There may be other sites worth looking at from a Google search. I used the search term -
