- *payment gateways* in Canada: [Shopify](http://www.shopify.com/payment-gateways/canada), [Chargify](http://chargify.com/payment-gateways/) list; I get free processing on first $1000 with [Stripe](https://education.github.com/pack/offers)
- [credit card form](http://designmodo.com/ux-credit-card-payment-form/) ux from Designmodo
- workers: using a free instance of IronWorker and assuming 5s runtime each time gives us a poll every 6 minutes. Zapier would poll every 15 minutes but already integrates Stripe and FB.
- use [DigitalOcean](https://www.digitalocean.com/) as a GitHub Student (@bath.edu email) to get $100 in platform credits which translates to 20 months on the slowest (fast enough) dyno
Let me call you every 3 months to ask how you are doing, how you are using the software, what can I improve, and you will get 3 months usage for free. The idea is to keep in touch with the most loyal customers, to hear them say how great/shabby the app is. If they don't want to talk they can always pay for the Business Plan.
If someone stops using the app, send them an email asking them for a good time to call so I can make things right. They would get 3 months usage as well.
