What open access journal can I submit with almost no money
I recently published a conference paper (fee was around $500). The paper received good feedback and was well regarded in it's field. After a few weeks, I received an invitation to extent the work for a journal publication published by the same organisation. As I was invited, there'll be no publication fees for the journal.

It's a bit of a long shot, but if you target a small conference with a specific interest and an associated journal, it might be worth a try. 

Disclaimer: I didn't publish at the conference for the journal and the outcome will depend on many factors, such as your research and how it is received. 

Wish you lots of luck in these hard times.
