Yes. Katie has a wide network of trusted colleagues across Italy and abroad. Contact us and we'd be happy to put you in touch with an excellent guide for historical or culinary tours.
Katie has many resources for dining and drinking in Italy and beyond. You'll find her Rome tips on her blog (especially this post) as well as in her many articles and books, and e-book. She also has two mobile apps for iOS devices ("Katie Parla's Rome" and "Katie Parla's Istanbul" and a number of online city guides.
Katie moderates comments, so maybe she hasn't had the chance to publish it yet.
Katie writes the blog at 3am after her two full time jobs (touring and writing) so give her a break, will ya?
Maybe. If your idea jives with the Katie's philosophy, she'd love to read your pitch.
