Fiber Terminations - SMF SC Ends

I have an electrical engineer that would like me to replace damaged single-mode SC connectors.  These go into a small industrial switch.

We have a Corning kit in the office.  It looks like this kit: UniCam High-Performance Installation Toolkit LC-SC and ST Compatible CORNING-C TKT-UNICAM-PFC.

I have never worked with terminating fiber.  This will be an outside job 2 feet off the ground and no fiber patch panel (so I can't work on the fiber ends on a nice surface).  The fiber comes in, goes to an adapter, two strands come out and has the SC termination.

Is there any type of SC end for single-mode fiber that will be easier than using this kit?  The cleaving does not look to bad, but the ends can be pricey if several tries to get it right.  I either need to find cheap ends, or a better method.   I suggested contracting this out (like they have in the past), but they feel I have the skills to figure it out. 

What is the best SC end to get for this kit, and will I be walking into a high-speed nightmare?  

Thank you
