Hi I am Jose Iglesias, I´ve more than 3 years of experience in Wordpress and Moodle. Let me say you that you don´t need to pay for that theme, you can use a free theme and integrate Moodle that it is the best format or we can call it a specific theme for all e-Courses, so.. we can explore in free themes. But if you prefer that, no problem.
I read your project description and I understand the requirements and I am ready to start on your project.
Let me help you.
