Hi. I'd love to help you with your site.
I'm based in Sydney (in fact, I used to work in St Leonards) and I'm very happy to meet in person to discuss your project.
I've been developing websites and web applications (large and small, simple and complex) for more than twenty years. Clients have included small businesses, large corporations, and universities.
I have expert level skills in HTML, Javascript, (including jQuery and Ajax), JSON, CSS, PHP, Perl, MySQL, WordPress and much more. I have developed several REST APIs, and created interfaces to several others. I have debugged and modified WordPress themes and plugins, created custom plugins, including some that integrated with other plugins (like Woocommerce) and was even asked by Automattic (the makers of WordPress) to debug and modify one of their own plugins.
I can create new themes or modify existing themes. I've recently completed a major project for another site that utilised the ACF plugin extensively, so I'm quite familiar with it.
My offer assumes a standard WordPress build with the custom aspects you've mentioned. I can also arrange hosting and domain registration (extra cost), all installation and customisation, and can handle ongoing maintenance and upgrades.
I also have extremely strong skills in creating custom WordPress plugins. I have developed countless custom plugins for clients, from small to extremely large and complex, including full-blown web applications. Please check my profile for samples.
