What type of horse do you think I would work well with? where should I get him/her?

I like to jump and like to ride horses with a more on the fast side gait. I would board him/her at my nearby stables. I have been riding for 4 and a half years. I am at an advanced level now, but would still enjoy a well tempered trained horse. I have a light rein and ride english. I am patient and I love horses. I LIVE TO RIDE =] Should a get a gelding, stallion, mare, or maybe a filly or foal. If you need anymore info just ask on your answer. THANK YOU =]
