|Consider just getting a section cut-to-length from Home Depot. Go to their electrical department. They have a section stocked with RJ-45 ends, crimpers, face-plates, and boxes of cable. You can also go towards the end of the isle where they will cut you a section to length.|
The most expensive part will be the crimpers...but, if your job/hobby involves messing with your network at all, from time to time, a pair of crimpers comes in handy for occasions such as these....so you can make a quick patch cable....a little 4" uplink cable, or a quick repair when a cable end needs to be replaced.
If you really wanna go cheap...a small flat-head screw driver can be used to "crimp" the ends - but that's really tedious.
