Wordpress Setup

My website [login to view URL] I want to make some level price, which aplicable for specific category only, etc. Example, hamba tuhan category is free, but gereja category pay $5 yearly and the rest pay $10 yearly and so on to setup. Then, paid category listing have differently with free categories, example have background color etc. I think any mistake on my currently setup because anytime to make new add listing, redirect to start up website again. I need to fixed asap and will start soon. Please give me your reasonable cost Thanks
