A group of us tried this last year - and some of us are still plugging away
It was called the Condado de Alhama Rental Management Association.
About 15 of us chipped in £10 a month to pay for ads on golf websites etc in the hope of generating some interest.
We had our own website, 'committee', organisation etc
Unfortunately, I think most people were expecting too much too soon, and, as there were not a lot of enquiries generated, one by one, the 'members' dropped out
There are only about 3 or 4 of us left, but we're still paying our £10 a month in the hope of building up a fund that can be used to start advertising again when things pick up a bit
Anybody interested in joining us can drop me a line
Regards
PB
