Triple monitor arm 1x Ultrawide (44' to 49") 2x smaller 27" (can't find)

[JeffJK]

Budget (including currency): upto $300 (AUD)

Country: Australia 

Games, programs or workloads that it will be used for: Office work

 

Other details:

I currently have 2x 27" monitors, and looking to get an additional/3rd monitor, however it'll be ultra wide between 44" to 49".

The configuration I'm looking for are the 2 x 37" Inch monitors at the top,

And the Ultrawide on the bottom as my main.

 

I can only seem to find 1x monitor arm per 1x Ultrawide.

Or 3x monitor arms at upto ~32" inch.

 

Can anyone assist finding 1 monitor arms that supports 3x of the mentioned monitor sizes?

I'm looking to spend upto $300 AUD.

 

Thx in advanced.
