Hi community

I am making a social network site for Danish Minecrafters (The game Minecraft). And I have been looking high and low for a plugin/module where is possible to login with ones Minecraft logins. I know plugins are available for Wordpress, but I have not been able to find anything for Joomla. So here is my questions, would anybody be able to code something like this for Joomla, so it works with Minecraft, as I am not able to do it myself.

If so, please present yourself and a estimated cost for this sort of work.
