Why did Georgia colonists come to the colony?

Oglethorpe had a friend who died of small pox in a debtors prison. Back then, debtors prison was basically a death sentence, unless, someone bailed you out. Oglethorpe had an idea... He presented his idea to the King. They would send debtors to Georgia, aka the debtors colony, the debtors would get to start over fresh. Georgia would also serve as a buffer between Spanish Florida and English Carolina, South Carolina had many goods at that time. However, less than 10 debtors were sent to Georgia because Oglethorpe did such a great job advertising how great the new colony would be.
