Recumbent - Where to find a fork?

So here's the deal. I'm part of the American Society of Mechanical Engineers at my university and this year one of our projects is to build and race a human powered vehicle, essentially a recumbent with a fairing. Right now we are just trying to get a rough budget together. I've been looking around to see how much it would cost to buy a fork but haven't found anything useful. I even checked at my bike shop but they didn't have anything. I don't have many specifics on sizes yet but we're pretty sure we'll have a 20" front wheel and are looking at road caliper brakes. Also, it would be nice if the fork were somehow built for speed, not necessarily comfort like most of the recumbents I see around. Anyway, I guees all I'm really asking for is if anyone knows of a place where I could get prices for recumbent forks. Or even if you personally have any idea on what it would cost that would be useful.
Thanks for your help!

It's going to be tough to get the right fork without knowing the overall design. On the other hand, if the frame isn't designed yet, you can adjust the geometry to give you decent handling with a particular fork. Get yourself a copy of "Lords of the Chainring (http://129.79.22.9/linear/wymsweb.html)" by Bill Patterson before you lock yourself into a design.

Here's a couple 20" wheel forks:

For a recumbent-specific fork, you should probably contact one of the manufacturers- Bacchetta, Volae, and Bike Friday use 20" wheels, so they're who I would be asking first.

Maybe you can take exisitng bikes (bought used or even junked) and cut the frame up into useable parts for your recumbent.

There are a multitude of DIY instructions out there on the internet on building a recumbent from diamond frames.

Good luck...sounds like a great deal of fun!
