Setting up a SH tank is much simpler than reef tank. I assume you have read and find out some basic of keeping SH. Equipment wise, a tall tank with live rocks (add in a bit of plastic nice red/yello/green colour seaweed will be good), just need a simple light, a good skimmer, filter and ofcos' you need the tank to be cycled before intro. in the SH. Food wise- best fozen food like Mysis or you can feed them with small live fresh water glass shrimp. All the equipment are easily avail. in most of the marine LFS or you can get all the things at Serangoon nth. 'Pet street'....
