Is there a virtual machine image that comes setup sharetribe community edition?

Hello All,

I am working on a non profit project and need to start with something cost effective. Initially to evaluate I would like to self host the community edition and work on the changes required to customise the website.

I do intend to make the changes open source but I am not a ruby developer. Hosting a PHP website is easy but I am finding it rather difficult to host sharetribe on a linux machine. I tried following the github instructions but I just can’t seem to make progress.

Heroku version isn’t cheap to begin with.
If this is possible then it would be great but I would like to know either way.

regards
Ankit
