You can pretty much use any in sump, and hang on... Can I ask why you want to go with a wet/dry? Just an opinion but I found it much easier to just go with a sump where you can control the water height much easier. Also throw in an ATO system.
As far as skimmers go, i would take your measurements and go on marinedepot, defosterandsmith, also amazon. Look up skimmer by measurements, and them just find one in your budget. When you find the one you like, you could just do a search for that skimmer online and go from there.
