There are several reputable engine builders who can help answer your question.

They're probably going to need to see your old crank to tell you if it's worth rebuilding or getting a new one. Anyone that can build a crank can bore cylinders...usualy.

 

Try Jeff @ FAST Racing or Jim @ Passion Racing. They can both help.

 

Search for either on this board..you'll find all the contact info you need to know.

IMO the stock crank isn't worth rebuilding. Its not a very good design and therefore isn't 100% rebuildable. Generally when your crank lets go you get some grooving and scarring and it'll never be "good as new". You can buy slightly used ones off ebay but you're taking a gamble. My advice is to go with an aftermarket wiseco or similar. You can buy em already welded and ready to go and they're 100% rebuildable if you ever have this happen again. While your at it, you might even check your wallet and see if you can afford to move up to a stroker or at least a long rod version. When you compare the numbers its actually not that much more expensive.
