Hey there. I'm going to reply to you without looking like a whore for the company I work for.
If you let me know what niches you're working with and what type of galleries you build I will try and point you in the right direction.
Of course getting some comments from other submitters would be a good idea too.
You can hit me up on ICQ (498-202) if you have questions.
Edit: I should mention that I run Submitpasses for GTS...
