Lens Cleaning Inside

[EWMEvanita]

I've noticed that some of my longer zoom lenses have little dust specks underneath the lens. Does anyone by any chance know about how much it would cost to get them cleaned and where I would have to take them.
Thanks

If the dust isn't affecting image quality as most don't, I'd just save the money and forget about them.

With some designs it's very easy to remove the whole front element group and clean the inside of it.
What model lenses do you have?
