Shawn: You're correct most solder preform manufactures don't want to sell preforms without skinning you alive for tooling charges!!!
Considering alternatives, can you print or dispense paste? It would be mucho cheaper. We've talked about using paste in through hole applications before on SMTnet. There's a bunch of good information in the archives!!!
If you truly are just doing a few boards, just get a hand dispenser (like a caulking gun) and squirt some paste on the pins you want to reflow and git goin'!!! Blank them solder preform not suppliers!!!
Good luck
