CAN SOMEONE PLEASE HELP ME GO TO JAIL?

I was given work release. I don't have the money to go sign up. The deadline for me to go sign up is in a few days. I just want to go do the jail time instead and get this **** past me. Can anyone tell me how I do that? Do I go put myself on calendar at court and tell the judge ide rather do the time in-custody? Or do I tell my probation officer? Can anyone that's had this situation come up too, please let me know? Or someone who might just know what to do? the advice is very much appreciated? Thanks.
