If I understand the job description correctly, the Top 100 list and the Bass Online Store need to be integrated into the rest of the main WordPress site. The Top 100 is a PHP feed script and you want to move to Opencart for the store. You want the integration to be seamless and, most of all, you want the components to work.
I have lots of experience with WordPress, HTML, CSS, PHP, and Opencart. I've modified Opencart themes and know the code structure. I have lots of web development experience using the same platforms your site uses. I'm very detail oriented. I want things to look right.
I'm sending you a private message that outlines the notes I took while investigating Bass Online. You'll also find more about my past work and my credentials in that message. After reading it you'll know you can rest assured you will get what you want. I guarantee it.
