Horseback riding wanted!

Horseback riding wanted! - Hello dear horse owners!
I'm looking in Tyrol (Innsbruck and surrounding area) a riding share.Actually, it is completely indifferent to me what breed, but the horse should be trained and also be big enough.
To me:
-12 years
-take professional riding lessons for about 1 year
-like to do dressage and also like to go riding
-do not have a riding license
-can only jump over cavalettis so far
-am responsible, very animal-loving and sensitive
You will get more information if you write to me.

It would be good if there would be riding lessons at the stable, but it does not have to be (I will take some myself). And if it is obligatory to take riding lessons with the RB, that would not be a problem for me.

I would be glad about your answers!
Greetings Chiara
