Guide Service in Black Hills?

I'm heading out to the black hills, SD for a trip and I'll have the chance to fit some climbing in. I'm a first year outdoor climber and have heard great things about the climbing around the black hills, specifically at the Needles.

Can anyone provide advice on guided services around there? I'll probably have a single day to go climbing.

Thanks!

Thanks for your reply! Do you have experience with this guide service?

I do, and they were excellent! Very friendly and knowledgeable, and they were very accommodating of my schedule.

+1 for a great company. Owned and operated by great people.

Do you remember what courses you took? I see that Sylvan Rocks has a 6 hour and 8 hour courses at different locations.

Can anyone recommend any particular course?
