Looking to trade 50 Gallon Tank 36*18*18 for smaller (or buy) - $25 (Placentia)

I have a BIG tank that I'm looking to downsize on.
The measurements are 36 by 18 by 18.
Picture included.
I am moving and I don't wanna sell my beautiful Australian Children Python and I think I can sneak her in if I have a smaller enclosure.
I believe this is a 50g tank --- see picture.
If you have a smaller tank with a secure top (my snake is 40" long so she could easily bust out of a smaller tank) then please let's trade.
I hold my snake so often that she only uses it for sleeping.
and shedding.
If someone could please trade me I might not need to sell my beloved snake and keep her.
I really love my snake I've had her since she was a baby (8") and now she almost 40" long.
I hold her everyday, she wraps around my neck while I work, clean, make dinner and go to store.
Please help me.
Please trade with me or let me buy it.
I don't have a car but I'm in Placentia across the street from Placentia Police department/ Library.
Contact me ASAP!
