I know this is old but Monoprice has Cat5 wire ends and the crimping tool for very little money and they work great.
I have been making up my own patch cables for the new house. 100 ends for $8 and the crimper was only $6. I have lots of short cable from the extra wiring left over after termination of them into the phone box and router etc. I now have cables from as short as 6" to 8ft lengths. It does take a little bit of getting used to to make them up and be successful as the wires can not be untwisted after the cable end or you loose some speed through the wire and it may also cause erroneous transmissions through it.
Also note there are 2 ways to wire 568A and 568B the only difference is which pins you use for the orange twisted pair and green twisted pair as they are swapped for each type. 'A' has the green pairs first and B has the orange pairs first but for a patch cable this doesn't matter just keep them the same on both ends
