you should be able to put her in under the loan section. sorry i haven't put an advert on myself so don't know but i know when i was looking for a loan horse there was a section for it. if you can't find anything else then i suppose you could put the advert in under £1000.
I was looking for the loan section yesterday and couldn't find it felt a bit of a twit to ask where it is but can anyone point me in the right direction please
All i ever did was to go into the Keywords bit of the search and type loan and then select your region etc. Also try equineadverts.co.uk they have a specific loan section as do ---------.co.uk.
Hope that doesn't count as advertising but they were really useful!
