trying to search for recording studios which have resources to record a grand piano. I know there aren't many around and I'm having difficulty finding one.
Well you can't want the best of both worlds can you? Grand piano = big studio and adequate equipments to mic up and record it in a good acoustics = expensive studios. Low-end studios are small and can hardly house a grand + inadequate equipments to mic a grand... If you are serious about it, then I guess should save up for it. I don't think there's any budget studios around that house a grand? Perhaps you can contact those studios recommended above and see if you can work out a deal? My 1 cent worth.
