I recently added a section of helpful deals / promos / freebies to http://leanpub.com/freelancedeveloperbook/
The selection is based on first or trusted second-hand experience of the products in question.
However, I've been thinking that it might be good to cast the net wider, to be able to offer newbie freelancers more: so, if you make something that will help indie devs be better indie devs, and if you're willing to offer them a decent discount/extended free period/something, we should chat. My email is in my profile.
