I have 12+ years of experience with diverse technologies working with globally respected companies, building infrastructures and software from scratch, programming complex mobile applications, managing admin systems, developing websites and e-commerce solutions utilizing: JavaScript, AJAX, PHP, HTML5/CSS3, MySQL + MSSQL, SOAP, Android, C#, Java, OpenSSL, + more.
From your project description, I have no idea how large or small your website is. so this bid is a little bit blind. This bid should be enough to cover development of a fairly large site, however.
