I do humanoids and my ref sheets are currently open. I do both SFW or NSFW. Any gender. All refs are drawn uniquely and do not use bases. They will come with swatches, and can include text if you want to.
Basic sheets start at $45+ and will just have front and an eye close-up, Simple starts at $55+ and will have full front, partial back, and eye close-up, if NSFW genital close-up too. Complex has full front, full back, eye close-up, and if NSFW genital close-up and can have other close-ups too, and starts at around $100+. I also do some more dynamic reference sheets which I can personally quote a price on after getting details.

Examples can be found in my gallery under the reference sheet folder: http://www.furaffinity.net/gallery/naughtyangel/
