Looking for an upright/double bass (Fresno)

I’m a self taught luthier/bass player looking for an upright bass, hopefully for a deal.
I’ve been playing various stringed instruments for years and I make guitars and stringed folk instruments by hand - I’m looking for an upright both to play as well as learn how to build/maintain since I have never owned one before.
I’m interested in any upright basses of any size/scale, whether currently in playing condition or not.
My budget is limited but please let me know whatever details you can about the bass you have available and what you would be asking for it.
Thanks!
