Horse Hands/Human Height help asap?

Hello Guys,

Could someone please help me?
I really need to know what sized horse I will require, I am 5'8-9.
I was told 15hh would suite me but I don't quite trust their judgement and as I am thinking of extending my family in the horsey-sence, I need help on the asap.

Also, does anyone have any advise they could give me for 'purchasing' my own horse. I have had my own horse before, and I am a beginner (taking lessons still as i had on/off lessons throughtout life) but very confident rider - how can I be taken seriously, as most enquiries i have made, i have been turned away by what seems to be some form of 'your not experianced enough for this horse' attitude.

Sorry if that insulted anyone, but please help! Please! Asap!

Thank you!
