Zib, I'm with Caleb on this one. $300 worth of labor, hell, I'd be ashamed if it took me a single hour to replace an existing line with a new one. Buy an extra ten feet of line and a splicing kit and video, spend some time learning how to splice in whatever the end fitting will be and consider yourself well paid by the savings.
Or run a messenger line with the old halyard, then drop the new line and eye off at a shop and have someone make the splice. That surely can't cost more than $75....and you can still feed the new halyard "backwards" with the messenger line that way.
The rigger's time is certainly worth money, but three hours at a hundred apiece to run a halyard...I hope that includes a titanium shackle, because the price of gold is only $1600 an ounce these days and 24k plating doesn't need a dollar's worth of it.
