Wheelbuilding / Wheel Building / Wheel build help

I have a pair of tubular rims, laced to old Campagnolo Record hubs (the ones with the oil hole).

I would like to switch these over to clincher rims, but I have no idea where to start, or what I'd need.

I've trued wheels before, but never built them from scratch.

I "think" I'll need:

• New clincher rims
  
• New spokes?
  
• Rim tape
  
  

Tools:

• spoke tensioner tool
  
• oil
  
• truing stand? (would it be possible to use my front brake for this? (I only have a front brake).
  
  

Or... would you recommend taking it to my LBS and getting it done? If so, how much should I expect it to cost?

Any forseeable issues with switching these hubs from tubs to clinchers? (Not sure if hubs need to be specific to a certain type of rim).
