Tractor supply has a large selection of standard hydraulic hoses. I'd give them a try.
We have a komatsu mini excavator that has needed hoses left and right. The fittings are metric and not really comon. We have the local hydraulic shop make them for us. He charges a pretty fair price.
When someone builds you a hose the type of fitting plays a large part of the overall price. Some places charge quite a bit for the crimp (labor/machine use). Another local place wants $7 a crimp so each hose is at least $14.
