If you can get a spopke wrench you can true it yourself. On a front I like to add tension on the spokes to bring it into true. After it is true grab parallel spokes on each side of the wheel and squeeze the heck out of them to stress relieve the wheel.
ON a rear wheel I only use the non-drive side spokes to true it laterally. This is on a rear that I have built or checked the drive side tension with my tensiometer.
