Customize a Memberful Theme CheckOut Process

Hello, I am using [login to view URL] to take payments and I now have this theme to take payments [login to view URL] I would like to customize it and have my logo and all the process in spanish. You can learn about how to do it here: [login to view URL] The customization it is basically put the logo at the beginning of the order, change the background to white then have the text in spanish. Fairly simple. Also you can create a free acount so you can see how it works from the inside. I want the project done ASAP so If you have a lot of work then this job may not be for you. Thank you
