Fix and complete a wordpress plugin

Needs support to complete a plugin that i wrote. The plugin actually create and add a new template in wordpress. This page template is a fullscreen page with an iframe inside(and some parameters in the iframe url) I need that the plugin create also the page with the name "customers area" using the new template added by the plugin. This plugin has an empty admin page(in the wordpress menu) and i need to add image selector, to choose an image from the wordpress image library, the image url will be used to set parameter to be passed in the iframe's url, for example "logo=[login to view URL]". So i need remote support (by teamviewer or similar) to finish this plugin as above described. Do not contact me if you are not skilled in this. the wordpress website for testing is [login to view URL] Attached the current status plugin.
