I need to change the hosting... I was using the free plan of Pagoda Box for developing. I am changing it on the next days. I already payed for a digitalocean server.

I know about invoiceto.me and many others similar services that do the same. The thing is I didn't want to fall in the "I had a great idea but its already done". I think I can continue improving it and offer best features.

Thanks for your feedback...
