sjsheng,
actualli i had a diy 2ft sump(five plan) with stand. wanted to continue wif the main but due to busy over my wedding so didnt hv time to finsh it.
i can sell u sump and stand for 40bucks if u need. gt few kgs of corals chip, bio balls, FOC for u.
like wat bro Marinesavy said, u may try getting a 2ft glass tank from LFS then get any glassmaker to do up a partition and hole for u.
i believe tat will cost u less than $100?
PM me if u need. Free delivery for u too!
