+ 1 for the Surly Ultra fixed/free hub. They're very good and very reasonably priced, *and* you can get it with a hollow axle to use with a QR for easy and fast non-derailleur shifting.
I'll be interested to see photos and descriptions of your "multispeed singlespeed." As to chainline and # of cogs and rings: modern derailleur chains let you can shift up to 12 in back! Me, I use one of my hoard of Surly Dingle cogs for my Phil fixed/fixed wheel (QR attachment so it's very easy to shift, tho' of course you need horizontal dropouts), and White Industries still offers its DOS 2-cog freewheel. And of course you can still occasionally find Sturmey Archer multispeed fixed hubs on eBay; I have a TF (direct and 75%; wonderful simple hub with very very little lash), TC (direct and 86.54%), ASC (direct, 90%, 75%); and a lackluster mofern and still on-market S3X 3 speed fixed hub (but threaded driver so it will accept single speed freewheels) is still available: direct, 75%, 62.5%).
