Plugin Customization

I am looking for someone experienced in PHP and Wordpress Plugin Customization. I have used Simple Membership Plugin to restrict post for various membership label. When I post for a membership label everyone (Other membership label member) can see the post on category page. When he (Other membership label member) click the post he got notice "This content is not permitted for your membership level." My requirement is to hide the post on category page/archive page for who has no permission or has restriction to see the post. I think simple "if condition" can hide the post. This is a quick project for someone with excellent PHP skill.
