There's nothing that looks like a date in the serial number but there is a "17 12" etched on the back which maybe corresponds to 2012?

Added to that, ASUS and ASRock boards use the shaded side of the polarity circle to indicate the positive side rather than the negative side, so it's something to keep in mind when installing new caps.
Damn... ok. Well here are the total counts:

OST RLX 6.3v 1500μF x5
Chemi-con KZG 16v 1000μF x4
Samxon gk(m) g7a 6.3v 1000μF x19
Samxon ks(m) g7a 16v 100μF x11

Which caps would be suitable replacements? What would be the estimated total cost to have it done professionally? I know this site would charge 100, which seems decent I guess, although I wonder if I could get a discount considering the board is still working fine, so no problems would have to be diagnosed. I don't know how much that is factored into the cost.

Other than that, how would I find someone near me that actually knows what they're doing? Most repair shops around me just seem focused on phones or basic computer maintenance like removing viruses, transferring files, getting scanners working etc.
