We can analyze the following points and consider which one is more promising at each point:

First, the marriage proposal planner is a very creative job, which takes a short time and is impressive. Don't need too many details, just finish it in 1 hour.

Second, the wedding planner is a wedding process planner, paying attention to details. The basic time can be extended to about 3-5 hours, and everything else is a full-day plan.

Third, the difference between the two is that marriage proposal can be multiple small ideas at the same time, and the wedding lies in the coherence of the whole.

Are all good planning positions. If the idea is strange and short-lived, you can consider marriage proposal planning. If the consistency is good, consider wedding planning.
