Here's my advice :

take the from upper arms off yourself
IF you do suspension and under-car work,

get the 4 new bushings yourself,
but pay someone with a press to press them in and out, and to spot-weld
them after.
The pressing is not super tricky,
but I doubt the hammer method.

also, paint the spot welds, PLEASE ,
and then get a front alignment.
and of course, you need to know that the
other front suspension parts, like ball joints etc.
are OK in order to get a front alignment.

LISTEN !  I have seen a car come straight from getting a front alignment
when there was major play in
a tie rod !   - which makes it totally impossible to
perform an alignment, yet they charged the ( woman in this case )
customer and never mentioned the shot tie rod.

Poor workmanship unfortunately  is more common
in the car repair world than it shoud be !

Do it right and you'll be glad,
