Adjustments wordpress website

I need some scripting help with my existing wordpress website. It needs to be adjusted. Right now it has payment function (paypal) integrated which I want to be shut off for this period. Later on I want Ideal installed. Further more I need some help with the existing 2 forms and the way it is shown in the website after filling in the form. I think it shouldn't be too much work for an experienced wordpress scripter. Can someone help me out completing my website? So: 1. uninstall paypal function 2. adjust existing 2 forms
