Would any help someone get out of jail on a go fund me page if they didn't know them

My fiance is in jail due to a warrant for child support. His bail is 624 I've tried everything I can to get him out I've asked ppl on fb his &my family. So now I'm resorting to strangers he has been in jail since Friday he is a good man but due to this child support he can't seem to catch a break. The mother of his child knows he is homeless and has no income but refuses to inform the court of anything. No I know it's his responsibility to inform the court as well but he has been so focused on finding a job and a place to stay. For the past 10 up until a few weeks ago he was living in his car and when I say that I mean that. I just want him home I start my job tomorrow I can't even make it to the jail to see him due to me using the last of my funds on phone calls. I just don't know what to do.
