In search of a particular kind of desk
I've been trying to comb the internet for this and it may not exist, but I'm trying to find an L-shaped desk that is pretty deep (like around 24" of work surface; currently have 20" and it feels too shallow to have room for both a computer and any analog work surface like a sketchbook/notebook) and also the space under the desk is not cluttered with "stuff" like built-in filing cabinets that would impede being able to put your chair there. I have found a lot of almost suitable desks but then the space at either end of the desk's length is taken up by a filing cabinet or something. I kind of need all that space to be able to sit in front of an excessive lineup of computers/monitors that serve varying purposes.
Does anyone own such a desk or know of a store that might sell varied enough desks to include something of this nature?
Location: US, DC area
Budget: Under $2,000 but if the answer is that a higher price point is needed to achieve this, I will consider that a valid answer even if I'm not ready to buy it
Size wanted: See diagram and fussy description
Style: It would be great to upgrade from particle board but otherwise I'm not picky
Where I have searched: Typing "L-shaped desk" into google and scrolling endlessly in the results but I didn't do a good job of tracking exactly what stores I looked at
Online or real store: Online but a real store is OK if they can deliver
