Podio doesn't place many restrictions on your hosting environment. The only things you need to be doing are making encrypted http requests and consume json. That can be accomplished pretty much using any programming environment you can imagine. That's why we are able to provide so many client libraries: https://developers.podio.com/clients
You should not look for a specific setup that support Podio API integration because it will be supported on all but the most crippled hosting plans. Since you are not super technical I think the best for you will be to find the contractors you want to do the integration for you and let them steer you towards a hosting solution that they stand behind and can provide support for.
Does that make sense?
