Where to take my seat to get modyfied????

[LBZ]

I bought a Mountain Mod seat for my Rev and it fits perfectly height wise, width, but the foam is a bit too soft so I bottom out to the pan almost just sitting on it. Does anyone know of a place that does good work with seats to have a denser foam installed to stiffen it up? I don't want it to be quite as hard as like a BOSS is but I need to do something.

Any help would be great.
