If you are quilting for a labor of love that is one thing. If you want to make money see what you do as a business. What seems to be missing with the quilters are business skills. I have looked at businesses such as, The Quilt Cafe, price range for quilts $125-$703.
Chinchillas do not need extravagant plants, treats, whatever added to their diet. The more simple the diet, the better. Pellets, hay, and fresh water is all they need. Wheat grass is the only type of live plant I would give my chin.
Oats, dried seeds, and other grains are great to give to a chinchilla that doesn't eat much more than pellets and hay. These types of supplements can be a great source of calcium and other minerals. Once a week to every two weeks seems to be a good frequency for feeding it.
