What are the chances of being granted bail on a federal swindling case in SC?

I just found out I have a bench warrant in SC federal court for swindling 8 people by selling items online & not shipping them. It's considered a federal case because I received payment through the mail. The alleged acts happened back in 2007 and charges were filed in 2012. I just found out now about the warrant when the marshals went to my mothers home looking for me. The truth is I was approached online where I posted my résumé by a person claiming to be a drop shipper. I then sold items on eBay, & took the money orders from buyers, cashed them & sent most of the money to the drop shipper. The person claiming to be the drop shipper never shipped the items as promised. I was barely 18 at the time, I never intentionally did anything wrong. I do not live in sc anymore. I called a bondsmen & was told its likely the judge will not grant me bail. I do have family in the same county as the court. Will I be allowed to bail out? What are the usual procedures for this? I want to turn myself in
