What are the forks? If it’s Rockshox and you’re okay with doing some bike fettling, consider DIY.
I say Rockshox as it’s the only ones I’ve done. Others may be just as easy, don’t know.
Basic RS lowers service is simple. Get the kit from TF or wherver, check out some of the videos on doing it. Generally it’s loosen bolts at bottom, whack with mallet, pull apart, clean, reassemble and stuff new oil in, refit bolts. Possibly may have to do some seals also but they might be okay.
The top big wiper seals are a little more effort though technically simple. Better with a tool to knock new seals in. Again, may not need doing.
Rear basic air can service is likewise simple, especially the likes of Fox. Twist can off, clean up, replace seals, add oil, put together again.
