putting together something from warmoth is definitely not hard. the only parts i needed some help with was drilling for a bridge ground. for some reason they didnt do it for this body although they usually do on the strats and jazzmasters i've bought from them. and i just needed help securing the bridge pickup to the body safely. if you can set up a guitar, then thats most of the work right there. as long as you order everything correctly everything should be fine. you may need to do a minor amount of fretwork on their necks. inserting the string ferrules on the backs of their guitars is annoying. i wish they did that themselves but its not so bad once you get used to it.
best case scenario its only about $200-300 worth of techwork if you brought it to someone to throw it all together. depending on the guy. maybe even less. i'm still learning but the last jazzmaster build i put together was maybe only 3-4 hours worth of work including the setup. the quality is great and the options you have are much better than a stock fender.
i spent $1100 or so on all the parts for this guitar and i'd say the quality can easily rival a $2000 dollar guitar in terms of quality. maybe more.
