Honest question: What is it about Stripe (picking this one specifically due to having used it) that would take a month of work? Their documentation is thorough but -- at least last time I used it -- totally lacking in examples, so patching together a server-side workflow for creating and charging against profiles took a couple days of on-and-off work, but a month? I can see this if it includes other development on the project, but as far as actually getting the relevant parts of the API integrated and working, I'm wondering if other people's experience has been vastly different with this.
