Nice start!
Couple quick points before your next round of concepts and variations:
We're small potatoes here and will often have to use the logo in B&W so you should design away from complex gradations and subtle colors. Bold text and geometric shapes and solid colors will be best for us in the long run.
Would also like to see the tag line incorporated in all next concepts and variations.
I hope this feedback helps.
Great going! Keep 'em coming!
Best,
Mark
