Its hard to powder coat a section of a piece... Powder coating involves static in the "painting" process...

If it were me (but then again I'm a big DIY'er) I'd tape it and paint it myself...

Scuff w/ Scotch brite pad, wash w/ dawn THOROUGHLY, let dry THOROUGHLY, tape (don't half ass), prime and then shoot your paint before the primer stops flashing so you don't have to rescuff, rewash and retape...
