Wordpress Development

Hi, I currently own two Wordpress websites and I am in of someone who is able to make changes to the theme/pages of one and integrate it as a subdomain into the the other. One of the sites is an interactive teaching website that was developed a while ago by a company. You will need to pick up and understand how this was programmed and then make corresponding changes to it. Changes will need to be made to the homepage design and also questioning system. The original company is unable to make these changes. The full change list is the following: 1)Backup both websites and move the interactive site into a subdomain of the other website. 2)Become familiar with the interactive website. Learn how it works and how it was programmed. 2)Include a menu button on the main site so when you click it it goes into the interactive website. 3)Changing of the membership options on the interactive website. I want a certain section in the site to be free and not have the current monthly trial. 4)Change the logo on the interactive website. 5)Change the homepage of the interactive website-Removal of testimonial section, blog section and contact us (As this is now within another website) 6)Implementation of a mailing list (Mail Chimp Etc) 7) Changes to the question system of the interactive website. (This is all coded in Wordpress not with plugins) 8)Production of Logos/Buttons for within the interactive section of the website. These need to be replicated to the ones I have had before. So you will need to be able to copy somebody else's work.I don't know the font etc but you will need to replicate as exact as possible. 9)Payment Page-I need a contact form and a payment page in my website this will be done through Paypal. 10)Email addresses set up through my server. info@ admin@ support @ etc. I also want to do this through gmail so that will need to be set up. 11)Look at the UI and suggest improvements. I enjoy working with people who communicate well. I try to be as clear as possible with my instructions and like creativity. Any improvements I can make to my sites I would love to hear them.
