What is needed for this to work?

I have a project I am trying to work on and I need guidance before I can start the hiring process to get the work done. I am creating a article writer website for people to get more information about myself and order my services.

This Picture *Click Here to See* is an example of what I am trying to do on my order page. I am using a Wordpress theme for the framework and I need the necessary code for this input information to finish it.

As you can see, there is an input text box for the Name and Email; then they choose how many words and the number of articles they want. The total part automatically reflects the correct pricing to the choices. The bottom text box is a dynamic (dynamic because they can order up to 40 articles at once) text box that needs to be able to allow the buyer to input the number of keywords necessary. All this information is than emailed to me at a specific email address, with a subject heading for ease of use in the email address.

My problem is that I do not know what needs to be done to make this happen...I hope that I can get the needed help with this.

Thank you ahead of time for any and all responses.
