Just my opinion, but I think it's better not to involve money in these things. At least for me it would quickly kill my motivation, as I would feel like I owe people something, which makes it feel more like work than a hobby.
Did you know Sturmwind for Dreamcast, a 2013 indie game for a console stopped 15 years ago sold more than 25.000 copies? I am saying it takes time to make a good game like this and time is money.
