My personal advice... Is to hold off on a horse quit yet... ( Yes... I know that's a really really hard thing to do but... To take advantage of the resource you have found ! At the theripy stables ! Enjoy the horse friends you will meet !

Put the $ you would have spent on vet checks hay ... Hay delivery ... Tack water troughs, trough heaters ( winter's coming )

and take riding lessons ( iv ridden all my life ! Still... Take every chance I get ! To have a lesson ! ( I to am on a shoe string budget ! ) I clean stall every wen. In exchange for help

no shame in it !
I hang on the fence as outhers are taking lessons as often as life let's me to ! If someone says they know every thing about horses ? RUN ! ... No one dose ! Your investment in YOU... Will not be a waste ! I PROMISS you ! It will give you time to have your barn area finnished

and you can see what it will take to care for them in winter

make some riding buddy's

possibly

and... Take the time to find your soul mate horse friend ! And be able to be the best soul mate you can be... To your new fur friend ! Pritty is wonderful... But I've met some AMAZING ! UGLY HORSES ... Met and owned ! Lol
