CRM - Email Marketing - Tasks Management WEBSITE

We have being developing a website for over one year but we decided to changed the coder that is responsable for that. Althought the website has nice features, we need a more organized professional way of working. We need a top PHP and Zend coder. This project will start with a "core upgrade" of our website, ellaborating of a report with the details of the code, and them proceed with some bug fixing and new features development. We are looking for a long-term relationship with a coder/company. We need about 40 hours of coding per week.
