URGENT FOR TODAY: FIX some issues on woo commerce

Hi there, I still have some big issues on my shop. Well here is description and read it carefully: Product Calculation We use a plugin called "Role based prices" We use it to provide different prices for different user roles. Actually there's a bug in calculation of the price for "logged in users" The price should be TAX EXCLUDED on the frontend, but tax is added. We have put the price in the backend for that role without tax and it should stay without tax. There're some more bugs, which have to be fixed. Since I have big problems with other freelancers on that, I need a new one FOR TODAY!
