One thing to consider, hire a local where the boat is if possible. Most that I talked to, especially an older boat, want to inspect the boat first. Makes sense, plus you may think it's ready, but they may not and if they are local then it will be a lot cheaper if there is work that needs to be done before you leave.
I think I paid $150 a day when we were going down the Intracoastal and anchoring
at night and $200 a day when were were running 24/7.
Just one man, no crew. Now this was a sailing instructor, great sailor I'm sure, but mechanic
he wasn't. If your not a real competent mechanic
, make sure the person you hire is, you may need one on board
