Write your program in a text file.
Use MPASM to get a .asm file and .hex file
Use WinPic or ICPROG to "burn" the program into a PIC12C508A - one-time programmable chip.
This is something that might be worth looking into.

If you can't buy anything from ebay, there might be someone here willing to help, or perhaps you have a friend who could do it for you. I'd be happy to order it and mail it when it came in, but my paypal has not been working correctly.
Hope this helps!
Regards
P.S. I hope I didn't over-step my bounds by suggesting some members here might be willing to help. Let me know if I did and I can remove that part of the post.
I built a pickit2 the other day!.... Didn't cost any more than a tenner...**broken link removed**
If you ask someone to burn you a pic18f2550 with the pickit2 firmware. It took about an hour.... I also put a ziff socket on (all on a small stripboard).
Another recommendation for the PicKit here. Both Digikey and Mouser sell them, and claim "worldwide shipping", so they should be able to get one to you. Also they can be purchased directly from microchip.com.
