Tonearm Rewiring Vendor Recommendation

I have a Roksan Nima tonearm on my Roksan Radius 5 table.  I had to do some soldering to the wires as the terminate before connection to the cartridge.  My ground wire was frayed and they are not in perfect shape. 

I was wondering if anyone had recommendations on where to send my arm to have it re-wired.  Any recommendations would be greatly appreciated!

Thanks in advance. 
Do you have replacement wire set?
I just bought one from Needle Doctor.  I may still do it myself. 
Hi JB - I would contact Michael Wharton at Brit Audio ( for the job.  He does exceptional work and is very reasonable.
Also Johnnie at Audio Origami in the U.K.
