Room acoustic setup

Hi All

Is there someone in the Western Cape area who can do a room acoustic setup ie frequency measurements, speaker and acoustic panel placement? Ive setup a dedicated stereo listening room (pretty much a bunker under the house) 9m x 4.4m x 2.4m and it sounds pretty good, but would like some help with the technical part of it and fine tuning. Where i have dips and gains and how to fix it.

Thanks
