Wrapping is really quite easy as is epoxy application. The first rod I built is a 3113 and it turned out great. You can build a wrapping stand and turning motor for dirt cheap and its ads a certain level of enhancement catching a fish on a rod you made. The rod I made my dad for christmas actually brought tears to his eyes, it really was a beautiful rod!
If its just one guide that needs replacing, get a shop to do it...the start up costs arent worth the cost of a quick repair. Otherwise Brain at west coast spent 5 minutes teaching me how to wrap a rod...thats all it took, its really that simple and Dave at high water is always more happy to go out his way to be helpful. If its a rod you are looking to have built both dave and brian do top notch work. being from the north shore I have no exposure to the other shops.
