Hello,
I found your PHP form on WordPress post and i am very interested in your project. As a hard developper with experience developing many plugins in WordPress (consider about the hooks in wordpress, transients for handling cache, dropin plugin and nust-use plugin, communicate with an external API).
As a web developper, not a web designer, with experience customzing theme in WordPress (consider about creating options page in backend, creating or styling your theme from a moock-up having been designed for instance in PSD, creating or styling a responsive design from a moock-up).
I think you will find i have the skills you are looking for.
Please, take a look at my portfolio to get an idea of the kind of website i have developped ; and the fedback i received from my previous employer. Typically, i work in oriented-object in PHP, CSS3, HTML5, and Boostrap. I am wrapping up a project now and will have available today.
I do have a few questions about the requirements and would be open to an interview, with my account skype which is challinge-dev, or in the chat of freelancer.com. I will be online all this day, if you would like to discuss. Otherwise, let me know what times work for you.
Thank you for your consideration.
