If you wish to ride and train horses for a living thats a goal to certainly set. have you considered a degree in Animal husbandry? There are a number of schools which offer such a program I did a fast search and there are many.
As to having something to do as a backup, you need to focus on you’re specialty and the related degree program which can help you gain the best diversity.
There are also a number of professional programs for trainers and Animal Management type programs, Communications and political science are certainly time consuming courses which lend themselves to someone who would be thinking seriously about Public service or Governmental work of some sort.
I know and accept that folks have Various things which they like to do like say web sites. There are so many programs out there that do the basic work for you that it levels the playing field somewhat. To gain a Job in the field or to start a business doing that requires a few things however. you need a Body of work to show people examples of your work and how you do things for others. You would need more than the few you have admitted to doing. You would need I would think around a minimum of 10 to 20 sites to be able to give a number of different examples and industries you have developed web site for and that would allow people to see your work and make a decision as to your skill level and abilities.
the Best thing you could do in all honesty is focus in school, get a part time or full time Job in an area you like like on a farm or in some way working with horses or a riding school which are in areas close to you I also did a search and discovered some in your local area.
This forum is about prospecting and business and related topics and you have a ways to go before your ready to make that leap into a Business of some sorts due to your inexperience. You may have some good skills I do not know but from what I see in your conversation so far is someone who really yearns to be in a business he loves like working with horses and has a little experience doing that but has not paid his dues and become a Pro or professional in the field and have alot of work to do to get that experience and if I was in your shoes I would be doing anything possible to get the kind of experience in the thing I love to do and chase it like a Lion chases his prey day in and day out for he is always hungry and willing to attempt to do what ever it takes to get his next meal.
I think you have a ways to go before you can even begin to worry about how to prospect a new business when you do not yet have the skill set to demand money for the skills.
I wish you well, but you would do well to focus on school and what ever part time or full time Job you can get as close to the field you want to work in and gain some good experience and learn from some folks in the trade folks with a great reputation and outstanding in their field. Then once you gain some good experience and training from someone then begin to market your skills to those who use them.
While in school take a class in Marketing it will open your eyes and is related to the field you have already chosen in business related classes.
I went to school almost 40 years ago it took me many years to get to the point I wanted to be in and I was 48 years old when I started my first company and now have three companies a Limousine company, a Print Magazine which specializes in the limousine industry, and a Charter Jet service. All took a great deal of time and Money and I had to Market those companies in many different ways to many different kinds of people.
You can learn those kinds of skills! Some Whiz kids do it early in life, some like me do it late in life. Study hard, learn and grow and do it early if possible it will be more rewarding when you get to my age. LOL
