That's something we should be able to take care of for you! I'd say swing by your local Micro Center to get a quote, as the process can be a little different based on the components within a given setup.
Thanks for reaching out!
I mean if you want to pay them to do it sure, however it's totally something you could do yourself. https://www.ifixit.com/Guide/How+to+Apply+Thermal+Paste/744 Then you can save the money to put toward your next hardware upgrade.
Probably $30ish to do that + paste cost. However I would really suggest learning to do it yourself. It's very easy, as you just have to remove your heatsink, clean up the old paste with Q-tips and isopropyl alcohol, let it dry, then put a pea size amount of new thermal paste.
