Aww good luck! If you aren't already, try selling through the consignment store , and pick up the LTR to go with it if you can. Oh, and do the trick to get an Impressive reputation before you start, so you're not losing any money from your fish sales. Build a tiny pond at home and stock with deathfish, so you can catch them 24/7, and they sell for the most too.
Two weeks is a lot of time, you'll be fine! And I'm loving your story
