As a graphic designer, I highly recommend hiring that job out to somebody who has some training and experience in GOOD logo design! The ag world is so far behind most industries that advertise and brand their products because we don't allow people who know about design to do work we think we can do for ourselves. Yes, there is software that allows anybody with a computer to CREATE a logo...that isn't really the same thing as talent & training required to DESIGN an effective identity for your program. It doesn't have to be expensive, but like a lot of things, I would be reluctant to use a bargain basement "designer" based solely on the price of the product. This is the face of your program, and it will help build your brand and probably be part of the first impression a lot of people may have of your cattle. My advice is to make that impression count!
