Add some content and forms to my wordpress site

I have a current word press site that I recently installed. I have approx 4 to 5 pages. I have the theme installed as well. I want to add some content and some forms and functions. I also need the navigation fixed with the proper menu names i will provide. List of functions: Add my linkpoint merchant account to my site for accepting credit cards. Add my paypal account ( I can provide the code from paypal you just insert it into word press) I have several service packages (8) that need to dynamically connect to the buy now page. Example if they select the gold service pack for $29 it will carry over to the buy now with the correct pricing. I need to add a form (free trial) that is to be filled out and emailed to me when completed by a customer. Other work needed: I need my 8 service packages made to look professional, maybe put into a chart. But it needs to look professional. This should be an easy project to finish within a few hours to a day.
