I would ask yourself this question about expensive. If you don't have much experience with this, is the money that Heroku/EY would cost you really that expensive when you consider the time you will spend learning how to scale your application on your own and the possible service problems you might experience while you learn. Cliches exist for a reason and 'you only get one chance to make a first impression' is completely true. If I go to check out your site and it is slow or down, I won't be coming back. Most people I know are the same way.
