Hello,
I found your "Booking system for airport transfers" post and i am very interested in your project. As a hard developper with experience developing many plugins in WordPress (plugin which communicates with an external API like infusionsoft or twitter and what you would want, integration of a payment plugin like nmi, paypal, skrill, considering about the hooks in wordpress, transients for handling cache, dropin plugin and nust-use plugin).
As a web developper, 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, creating a website using AJAX with of a course a theme).
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 available now.
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. Otherwise, let me know what times work for you.
Thank you for your consideration.
