I see that you are located in "South West UK", so where are your nearest or convenient airfields? There are plenty based at airfields all around London, but are you looking for one nearer home?
I fly AA5A/AG5As, & I seem to notice at least one of them at nearly every airfield that I visit, so there must be a lot about.
Have you tried asking the operators or ATC, at your local airfields? They can usually tell you who has a particular type for hire.
