easier web content creation for Liferay

Hello I would like to simplify process of web content article creation in Liferay 6.0.6 The main idea is - editors don't need to have full access to templates' and structures' edition, They don't need many of standard liferay article creation features. They need simplified form. So I need to create custom web creation portlet. Main features: . It should be able to create some buttons - for example button "Create article in category A". It should load predefined template and structure, it should categorize and tag entry based on button configuration. It should create some images thumbnails. The portlet should replace standard liferay article creation and edition portlet for chosen group of users. We can discuss details in PMB Only experienced liferay developers please! It is simple project, but only for those who knows Liferay well.
