Grants will take a long time to lock down I suspect. Maybe fine if you can float the cost for a few months and reimburse yourself out of grant funds later, but there's a lot of uncertainty.

$50/day is pretty small relatively speaking, so just finding a local corporate sponsor and running an ad for them would probably work.

why pick up the phone if you could just put down a placeholder banner saying something like "do you want your company name here? write [an-email-address-thats-not-your-personal-mail]".

If the project is really becoming a local hit then you're bound to get contacted.

This is likely the most easy way.

Alternativly or additionally you can ask for donations on that banner. And a link where OP explains his situation, no profit, just costs, but like to keep the thing running.
