I have this crazy notion... but how do i get started... & should i even try?

hey all, you know i love dogs, they are like my obsesssion, i will watch any movie with a dog even if its not about the dog, will watch any commercial etc... they have been my passion since i was about 7 yrs old & i have been interested in training since then, reading all that i can & learning all that i can. while we stockpile money for a career leap, OH was thinking of offering horse lessons & helping ppl with their horses, & i got the idea why can i do the same with dogs?

the problem is I am not 'certified' offically tho i have what i would concider quite a bit of experience (tho i am always learning & willing to soak up knowledge) would i have a shot at charging for my services to ppl who are having probs with their dogs? just a thought (note this thread isnt a solicitation, just looking for advice on how to get started).
