I priced right angle connectors for paulbaptiste the other day.
Even with my volume pricing discount, Neutrik right angles are $6 a piece. Quality mic cable runs around $1 a foot.
Figuring in labor, the custom cablers on this site are offering very fair pricing. On the other hand, if you have time, and want to learn a relatively easy but valuable skill, get an iron and build your own. This will also save you money in the future as you can fix your own interconnects as well, though I rarely run into a problem with Neutrik connectors.
XLR connectors with their solder cups are one of the easiest things to solder. Plenty of online tips on how to do it well.
