Go to your LBS and bring your parts. Tell them your looking and would like a estimate. I would highly recommend to buy the tools and learn how to fix and build your own bikes. It's cheaper in a long run. I would recommend to buy used and build up. But if you want, buy new and figure it out. If you have a good LBS, they should load you up with a good bundle of parts and a good estimate of service. Keep in mind, most service is that same as buying the tools used in that service.
