You can center the steering wheel yourself if you pay attention and mark where you start from. Centering is done by moving both tie rod end adjustments the same direction. The hard part is figuring out which direction to turn each side, as some are both right hand thread, some are right on one side and left on the other. Based on where your wheel is, the adjustment should take very little movement of the inner tie rod.
You want to move the front of the tires to the left. So mark your starting inner tie rod position exactly to the tie rod. Then move the inner tie rod one or two full turns in one direction. Note which way the front of the wheel moves, then return to original spot. Do the same on the other side. Note for each side which direction you moved the tie rod to get tire to move left. Write it down!
Now from the original position, adjust both inner tie rods 1/8 turn in the direction that moved the front of each wheel to the left. Leave the nuts loose and drive it to check steering wheel center. Make fine adjustments until you get it straight while driving. Remember in order to not change the toe adjustment, you have to move both sides exactly the same amount. Tighten the lock nuts making sure the inner tie rod does not move.
