I would say to be patient and beat the bushes. A programming cable can usually be found on ebay for $20-30. The RSS programming software is harder to come by, but sometimes is available there as well, or folks will point to another source for it. That software does usually require a DOS system and a real serial port to be used, so a legacy laptop may be necessary as a "programming station".
Or you may find one of the local radio clubs (Hall of Science in Queens?) or NYC ARES, has a member who is already set up for this.
But if you can get the bits and DIY, the software isn't hard to understand, and you won't be locked into whatever you do on this round.
