Jamie, I know my custom stuff will be out of your price range. But if you find a gi you like, such as Bujin womens gi, professional alterations should be within your budget and should also be available locally. You note that for things to fit around you, the sleeves and legs are too long. Thus you should order what fits best around your body, wash them in hot water a couple of times, then get to a local seamstress/tailor. Best places for references are fabric stores, sewing schools, good quality dress shops or dry cleaners, the latter frequently employ skilled seamstresses.
I agree. I think most dry cleaners will take up pants for about 1000 yen and sleeves can't be too much more. Not sure about in America though.
