ehh drill it out a little more tap the hole and install a slightly bigger screw with the same thread u just tapped, no need for a new one, any shop will surely rip u off and take ur money to do this easy fix, i personally go to midas whenever i have to get engine work done but i have yet to know a good shop that will do things for a "fair" price. if u lived near me i could take care of it for u.
