I have a 65 gallon tank which I got drilled. I think it cost me about $60 including the bulkhead. I built the overflow out of some scrap plexi I had laying around. Then I bought an old beat up 25 gallon tank for a sump for around $20. Then I payed Bow valley like $10 to make me some baffles for it, siliconed them myself.

Return pump will require some research and could range between $80-$200 used depending on what you can find.

I hope this gives you a good idea of what you can do. I would recommend setting up the sump even before buying the skimmer. You'll thank yourself in the long run for having a sump, I promise.
