I found the Hombre disk to be extremely well featured for transferring data and writing back ADF images from a PC to an Amiga. If someone in your country with an Amiga could download Hombre and write it to a floppy disk for you, you'll be set. You'll only need a PC with either a floppy drive, a null modem (serial) cable, or a laplink (parallel) cable to transfer the data to your Amiga.
I'm in Australia so postage from here to anywhere else in the world generally takes longer than it does from anywhere else (except maybe New Zealand), but I can send you the disk if no one closer is able to.
For anyone who can write Amiga floppy disks and wants a complete transfer package for easily writing all those ADFs on your PC's hard drive back to your Amiga floppies, this is the package to get:
