I want to build a rack, and have no idea where to start

[tributeml]

Greetings!
(i'm new here, don't scream at me yet)

So, where to start...
i've got 4 snakes all in separate terrariums throughout my room, and man are they in the way. I've been thinking for sometime about buying/building a rack to consolidate space in my room but i have no idea where to start and/or what size i'll need since all my snakes are pretty different sizes.
What i have:
1 6.5ft Dumeril's boa
1 3ft Blood python
1 16'' Western hognose
and
1 (of course) 4ft Ball python

I would really like to get more snakes, but the stupid tanks take up so much damn space! Anyone have any thoughts/opinions on what i should do/build? I'm not really looking to spend over $350ish, but if i have to it's not out of the question, however that's why i figured building a rack wouldn't be out of the question either.

I guess my main concern is, what is the best way to store a tiny hognose and a fat dumeril's in the same rack system? seems like the dumeril's would have to be in a giant *** tub while the hog in a tiny one.

Thoughts? Opinions? Recommendations?
Thanks!!
