Great picture! We are also a company based in Nepal where this picture is taken from. Our company name is after another peak - Manaslu, which is a 8th highest peak in the world. We do Ruby on Rails web development. http://www.manaslutech.com
Yes, heroku will be a good option as you don't have to worry about web server, db and other setup. If you are a one man team bootstrapping your startup or project, heroku will save you a lot of time. On top of that, you can start free and later on worry about paying and scaling. I recommend to use beanstalk for git private repository instead of github that only provides free public one.
We are startup seeking work from other startups to build Ruby on Rails and mobile( iOS + android ) applications. We also build MVP for a flat rate in 6-8 weeks. We are very competitive and focused on delivery. Take a look at us at http://manaslutech.com/ or shoot us an email at [email protected].
