aMember Pro v4 Simple Plugin Needed

Hello, I'm looking for someone that know [login to view URL] API and aMember Pro v4 API very well. I would like to have a plugin created based on the already available gateway plugins, I've been told it isn't much work to take a sample plugin to understand the API and simply use it as reference to build the [login to view URL] add-on plugin. Please showcase your previous work, with customizing or creating aMember Pro plugins, it can be a sample of a plugin or customization of aMember Pro v3, since version 4 just was released. Happy bidding. :) As we are a startup our budget is very limited, lowest and most experienced bid wins.
