Problem is that they will likely only true it not make sure spokes are highly and evenly tensioned stress relieved so you'll be needing it again soon. A properly tensioned wheel will hold its trueness. If it were my wheel & I took it to a shop I'd ask for them to provide a record of all the spoke tensions. I provide that to my customers for their records.
Half our life is spent trying to find something to do with the time we have rushed through life trying to save
It's easier to true a wheel than you'd think. I was fortunate to have someone show me how in person, but there are videos that should be sufficient. After truing several wheels, I rebuilt a wheel from youtube videos.
A truing stand is nice but not necessary. A good spoke wrench is a must, and you should have one for emergency repairs even if you get the LBS to do your truing. I like the Park Tool ones with a square slot that grips all four sides of the nipple.
