Are you super cargo? Will you be required to stand a watch? Can you sleep if you don’t want to do your watch or it is too cold or raining? Is the food going to be steak not beans and rice? Will you need to cook and clean?
For $2,000 you should be a passenger not crew. If you must do crew duties then you should not pay more then shared cost of food. Split the bill at the store not a fixed amount a day.
Also don't fall for the "I will teach you navigation" etc so you should be paying me. I do this for free and a good capt will teach you anything you want for free.
Just my 2 cents.
