You can get the cable either way.
The issue would be the length you need. The unfinished cable would be best for your distance I think.
I do not suggest splicing a few 100 foot cables together - it's not the best signal.
You might find a length of finished cale in a search that is long enough

A hardware or computer store might be able to make one for you - but it's really easy to crimp the connectors. The color coded wires makes it easy to make a straight trough cable (looking at the connectors in the same direction, the wires match in color - the color itself is not important, just that they match in the connector)
