Need help finding a custom amp builder...

I'm very picky about what I want as far as a head/cab rig. I want a 500 watt head with a 4x12 cab and I want the whole thing to look exactly like this, except brand new. Weight is not an issue with me, I want my rig to look like a fridge.

Does anyone here know a custom amp builder who could make me one of these? I've had no luck searching on the internet and I had to cuss out a Sweetwater "engineer" who tried to interest me in one of those 50 watt toys Vox currently makes. I have zero interest in any other manufacturers or models.

Most modern bass amps/cabs either look like toys or have garish colors/logos that are an instant NO for me.

Is your intent to scale the speaker cab up to a more appropriate size for 4 x 12's, or just clone the cab as is, however inadequate it might be?

Thank you for your question. I want both the head and the cab cloned on the outside, and the cab the same size as the original (36" tall, 27.4" wide, 14" deep. VOX made a Valvetronix guitar cab back in the 2000s that was 4x12, although it was 160 W RMS in stereo and 320 W in mono. I've tried looking for the VOX AD412 cabs online but no luck. If I could find one, I'd have someone reconfigure it for bass speakers and more power.

Yeah, there's a bunch of custom cab makers out there. A quick Google search will yield you an array of options

You want a 412 Powerhouse cabinet. It's built like a fridge.

Then, buy a Mesa Prodigy amp.

Then, remove the grilles and tolex..

Purchase new grille and tolex material.

Re apholster your new rig.
 
I think the biggest obstacle will be cab physics.

If you could forgo the "4" x12 configuration and work with maybe 2 efficient ones or maybe 3x10 that cab might be ok. Not sure you've got adequate room in there for a quad of good 12 inch bass drivers.

I’m not gonna pretend to know how terrible the T/S parameters or whatnot would work out, but if we’re just throwing speakers in a box with reckless abandon, we could take a cue from the Berg HG series and have a rear firing and maybe a down firing driver. We could get all 4 12s crammed in that way.
 
Budget notwithstanding I'd probably do a fEARful 12/6/(1)? and sub in joined cabinets. That way the size/shape could be approximated without having to work out all the speaker volume requirements for 4x10" speakers into that shape/size cabinet. It would be monstrously loud.
The tolex/face fabric is just dressing.
The head I'd do a light power amp and a SA RPM.
Just 2c worth.
