Red Rocks newbie looking for beta

I'm going to be at a conference in Vegas during the first week of March, and was thinking of staying an extra day, hiring a guide, and doing a long moderate route. FWIW, I lead 5.5/follow 5.7 at Gunks, and lead 5.7/follow 5.9 on slabbier routes.

So the first question: Any route recommendations in the 5.6-5.8 range? I'd be interested in something at least 6-7 pitches, and had my eye on Solar Slab, but would like any and all suggestions for good long routes (short approach would be nice, too- would rather spend my time climbing than hiking!).

Second question: recommendations for guides or guide services?

Thanks!
