A bit of a conundrum

Trying to figure out what to get in order to grow my yarn business. I could upgrade my drum carder, get another wheel for production/plying/teaching, or get dyeing supplies. All are needed really, but I can only get one thing at a time :/ What to do?
I already know my drum carder of choice: Strauch Mad Batt'r, but the price tag.. $775. Would need a few hundred more dollars. How much would I need to sell? How do I sell batts and yarn?
The wheel is a bit harder to figure out. Used or new? Probably going to be used. The Babe Pinkie? It would definitely be portable, but would it be enough wheel? Close behind is the Ashford Country Spinner. Defintely not doable right now.. Then there are Heavenly Handspinning wheels. I really like the Stella Double Treadle. Affordable, but I don't know much about them, other than I used to have a kick wheel from the same maker.
Dyes will be coming from Dharma Trading Company. I should probably go get these first and get the wheel.... anyway!

This is what I'm working on. :) I still have another 2.5 oz to spin. It's hand painted merino top and I plan to Navajo ply it. Can't wait to see how it comes out. It may be the first yarn that I sell :)
