Define "configure DNS for WHM/cPanel".
There are a LOT of things that could be done under this guise, you're going to have to be a bit more informative here. If you're talking about moving your domain's DNS (nameservers) to cPanel, this can be done, but only on an individual basis, and nobody's going to do that as cheap as you're requesting
If you're after setting up the server so that it can act as a nameserver, by all means, you can have this done.
Next time, a bit more of a description would help :) . I'd love to work with you as long as the job is reasonable, but, if not, there's nothing that can be done. I DO have over 10 years of cpanel/whm experience under my belt, and can probably do what you need done, but you'll have to be more descriptive than just "configure DNS for WHM/cPanel"
