Hi. I'd love to help you with your website requirements.
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 also have extremely strong skills in creating custom WordPress plugins to deliver unique and exclusive functionality. 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 examples of sites, applications and plugins I've built. I can provide links to other sites I've built or contributed to, if required. The service I provide is professional, expert, up to date and highly valued by my clients. I've been doing this for decades, so I know what I'm doing.
I'm not totally clear on whether this is a project-based need or an ongoing need, as you've specified a fixed sum but your description sounds more ongoing. I'm going to assume a specific project, but please correct me if I'm mistaken.
Unlike the other offers made on this job (at the time of writing), I am actually based in Sydney. My offer is based on a major discount to my usual hourly rate and includes the Freelancer fee and up to 32 hours of web development, including Wordpress and coding. Additional can be charged at my usual rate.
