Advice to treating my muddy control room

A buddy of mine has a home studio and there's considerable mud. I'm a producer and not an acoustician by ANY means whatsoever but he's asked if I can help so I am expirimenting on his $0 budget:) He has about $500-800 to spend on treatment products (DIY Preferred) but nothing for an acoustician. I am experimenting with a UMIK-1 and REW software and came up with the data below. We're looking for general advice on what kind of treatment and where to install it (not looking for "hire an acoustician" as advice please. He unfortunately doesn't have a budget for that).

The control room is 10.5' x 17' x 6.5' (short ceilings). The monitors have been aligned with the Amphion Triangulation System and they are 3' out from the wall on an Argosy Halo desk. 6 racks of outboard crowd the room. The walls are floated and double sheetrocked with GreenGlue and ceiling hangs on iso clips, etc. He already has about ten 6'x3'x3" baffles up on the walls and about three dozen 1"x12"x12" absorption panels on the ceiling above him acting as a thin cloud (the good ones, not the cheap foam crap).

If left to my own accord I would:
- Add thicker bass traps in all corners (floor-to-ceiling).
- Add broadband absorbers at reflection points, especially on side walls and possibly behind the monitors.
- Enhance his meager cloud above with additional absorption thickness.
- Add diffusion on the back wall to reduce over-deadening and maintain a natural sound.
- Experiment with monitor placement to minimize low-frequency issues.

Short of throwing bass traps and broadband diffusers at the problem and hoping for the best, can anyone recommend a specific treatment based on these images? Any advice based on these screenshots would be quite helpful. I'd love to get to know this software better. Thanks a ton!:peace:
