How do you improve a job system that is simple

so im looking to redo my job system here that was made for fun. However, im not so good with getting ideas to improve the code sections.

The job system was made so it fires from client to server. How do i go about adding more effective details to it so it’s enjoyable to use and to complete.

The main idea of the job is to collect a box from point A, and place it outside by the trash and u get money. This is to simple and boring. But im clueless as to how i can improve this so it can look top quality.
