Horse people are generally conservative and traditional and with a tendency toward sophistication. Target audience is educated, wealthy and over 30 years of age.
I'd like the logo to include a hint of an equine theme, but I'm very open to other design ideas. And since green is in the name, I'm thinking green is a logical color, but I'm also fine with green being a secondary color as well. Horse show championship ribbons are blue, red and yellow, so those colors might naturally work into it as well.
Originally, this business was solely equestrian businesses with competition horses (think Olympic sports such as show jumping), so the tag line was: "when you win, we write." Now it includes other types of businesses, but if a designer would like to play with that it could still work out, I think.
Also, I'm flexible in having the LLC in the design, so feel free to leave it out if you prefer.
I hope this additional information is helpful. If you have any other questions please feel free to ask.
