this would work.. or this.. or with this!
....thats a PEX pipe fitting.. its a 3/4" female hose adaptor so you can thread it right onto the outside faucet. then the other side is a 1/2" pex fitting. youll need some pex pipe which is this..

..you can bury that line too and itll be alright. youll need some 1/2" pex rings which are these..
you slide the ring onto the pex then put the pex on the fitting... and you slide the ring into place, like an 1/8" from the end of the pex and crimp it. but make sure you get the rings and not shitty sharkbite fittings.. the rings last a really long time.. sharkbites are for people who dont have a clue about what theyre doing.. this is the tool youll need to crimp the ring, its really easy, the rectangle nub coming off it.. like where a diamond would be on a normal person ring. you squeeze that with the crimper and it locks it in place.
then on the other end of the pex line.. put a ring on it.. and put a hose valve on it and crimp it.. hose valve looks like this.. needs to be a 1/2" pex valve..
turn the original faucet you have on and you got water going wherever you need it to. hope this made sense.. probably your cheapest option if you do it yourself
if this post didnt make sense.. blame this -->
