first, you should jack up the front one wheel at a time and find whats loose.
Could be tie rod ends, could be wheel hubs, could be drag link ends, etc... If you jack up the wheel and it has play in it left to right but not up and down, its prob. tie rod ends. If you jack up a front tire and can wiggle it left to right and up and down feeling some play in there, its the wheel hubs. The wheel hubs and the tie rod ends have a huge affect on wobbles and they arn't something that can just be torqed. Find the loose ones and have 'em replaced.
A shop giving you a quote without even seeing whats wrong first is bogus. They should take 5 minutes to troubleshoot then tell you what it needs.
