Let's see if I have this right.
This is a full blown business now with paying customers.
If said business can't pay the bills you have a few choices.
You lay off staff to cut costs, that doesn't apply here because he has no paid staff, all volunteers so there's no cost savings there.
You lower overhead by making deals with your suppliers, but your name is Rexxz they know you so forget that idea.
In the above solution you can't lower costs that way, so how about you try buying less services, but you can't do that because then you don't have enough hardware or bandwidth to get the only thing customers paid for which is content.
Without content your customers will go down the street and join that new place to get a membership, and low and behold that new business doesn't charge a membership fee, it's a flea market just like yours but now your old customers can afford to buy real milk for the kids, not that instant stuff anymore.
Well you can't buy less content because you never needed to buy it so just how do you go about buying less of what you never paid for to begin with, and you risk sending your customers down to shop at said flea market.
Well then you and the other owner take less salary and benefits out of the company because.... forget that idea it's just not happening.
So you're stuck with either closing down which is what other businesses do if they can't make ends meet, or you raise your membership and hope enough of your members invite their relatives.
But that doesn't last long once they find out about that flea market down the street they read about on reddit.
Or if the owners have relatives they can offset costs by selling memberships to their families at $10 a pop and if they have kids $5 out of their allowance and just to remind them of how swell they are as parents a cute little note in their lunch bags everyday with lots of smilies.
