Customize CSS & Html5 pages.

I have an existing html5 website built from a website template. I have added to it a membership script program called [login to view URL], which is free but has very well structured application and easy interface control panel for everything. They make their money by automatically requiring connecting a payment and affiliate network to the each membership site that a person builds, in order to make money on the transactions and products commission system to the affiliates, like ???. Anyway, I don't anything complicated such as code modifying, i just need the CSS portions of the Membersgear pages for user login, sign-up form, user profile, etc so that those pages say the text I want to customize to my site name and products. In addition, my html5 template website buttons need to be configured to point to the proper links within the membersgear script/database, and I need approx 4 pages within my website template to be created that are like sales pages that explain the product then show buttons to go to sign-up, and one page that will have the pdf file uploaded to it then protected so that it is the product delivery page after they pay the $7.00 fee to become a member. You can click the following links to see the sign-up page and the user login page. These are generated from the Membersgear software, but I will not be changing the images, but only the black text on these membersgear templates. I want to keep it simple because i do not have a large budget, however, I do not believe this to be difficult work, maybe 2 hours of work, could be less. Here are those two links: [login to view URL] and: [login to view URL]
