Off the top of my head, here's an idea: Hopefully, you're involved in your industry's various online communities. Offer them an opportunity to try your gateway with waived/reduced fees for some time in return for using them as a case study. You potentially gain a customer, get free advertising (via their word of mouth), and extra fodder to throw around during your launch. They get reduced rates, personal help with getting your software integrated and potentially have a better experience handling transactions (right?). Alternatively, you could pull some stunts. I'm sure you're familiar with WePay's shenanigans. I think your FeeFighter's culture would do well with this sort of promotion. Think of something clever. (I've got nothing right now.) Launching a product like this is tough. You have to literally be in the right place at the right time. I'm certain you've prepared for this. I got your email and will kick the tires over the weekend. If you don't hear from me, reminders are welcome.
