as things are now i think you will have a difficult time starting a league without a table vendor's involvement. as it stands now only a vendor can become a charter holder.
i was talking with Jim Waterman last year at tornado worlds about my situation that is similar to yours. i was disappointed to find out a vendor is needed as there are NO vendors here just bar owners that own there own tables.
anyways Jim told me there was a chance in the near future that VIFA would lighten the restrictions on charter holders.
you could always hold a weekly/monthly DYP at a slightly out of your way location.
make up a foosball business card with some extras like foosball forum addresses, addresses of other locations, etc and leave them at locations, no reason you can't get a group of players in a 60+ mile radius together every week or month at a Central location.
