Good/well paying jobs

Hi all. I’m trying to save up for my wedding next summer and really struggling. I have 3 jobs and work 7 days a week but our rent is pretty pricey so it’s just not enough. I have my ba degree in psych but need a masters for most positions so I’m working in childcare and event management for the time being. I make about $10.50/hr during the week but really enjoy my job. There’s a Dunkin down the street from me that pays $11.75 so I know it would honestly benefit me to quit and go there. Can anyone recommend any other jobs they enjoy or make money doing on the side? I’ve heard selling on amazon is good money too just don’t know how to go about it.
