Yes Margaux, I fully agree. If co-working could mean cost reduction for big company set up in very expensive cities, it could be the opposite for smaller one I guess.
Maybe some "discount" co-working places exist in your area ? By discount I mean not much more than Starbuck, without Starbuck heavy traffic :-) There are some around start-up incubators usually : Chairs, tables, coffee and wi-fi :-)
Or maybe some associations in your area where you could get connected to some entrepreneurs like you who are looking for places from time to time to gather, exchange, and work ?
Just brainstorming here.
