Doing deliveries is a lot of fun and one can gain a lot of experience in a very short period. I am speaking form experience.
My best suggestion is to walk the marinas in Ft Laderdale and speak to people in crew houses and hopefully that way you may get daywork and something more permanent. Networking is so important and keep a positive attitude. Good luck!
P.S. If you get something and they are looking for someone I am available!!
