Why the hell do you want to keep paying out all that money!
Take the front drag link off at one end then check the full lock to lock of the steering box, centre the box and refit the steering wheel dead centre.
Fit the drag link roughly central (checking the wheels or by having driven it in a staraight line before starting work)
Road test to check, if the wheel isn't lined up simply stretch or shrink the front drag link to get it right, you do not need your tracking checked for this.
Somewhere there is a proper dimension for the drag link but I can't remember where.
the steering lockstops will not need adjusting if they were right to begin with.
If the balljoints were fully screwed in to the track rod (the one at the back) then you should have no difficulty in adjusting the tracking to get it right. This is a job you can do at home.
