You guys are way ahead of me. I just moved from the brick and mortar world and entered the digital world. My list is about 300 right now and I offer a free ebook and one free email coaching session. I have a membership site for small businesses to help them double their revenues. I really believe in the power of the list and come from a direct mail background.
If my list is too small I understand. Let me know if you want to trade, my list is growing about 2 to 3 pre-qualified leads a day. I'm using article marketing as my lead generating engine. Email me id you want to give me a try.
