Real Estate Listing Software

We are looking for a very experienced PHP developer, which recognizes the need of documentation. The goal is to develop a web based real estate listing software for real estate brokerage agencies. The software contains a multiuser CRM to manage contacts, leads, contracts and a time sheet. The CRM has to offer the opportunity to customize design (CSS, Logo) and language. The main language of the application will be German, so make sure that a translation is possible. Further the application contains a public website for real estate listings and an XML export function. The website has to be developed by guidelines which we will transmit on a later point. The XML export function, exports all listings to real estate portals by standard OpenImmo XML. This task has to be automatically executed daily. The software has to be developed in PHP with a common free framework in the background (Zend, CodeIgnitter, Yii, ...). The choice of the framework is up to the developer, but has to be explained. The framework has to match the needs of the software. As a database we would prefer MySQL or PostgreSQL. Everything has to be installed on our Linux servers by SSH connection. The first version should has to be ready not later than 8 weeks from time of hire. If you are interested in this job, please apply only if you are experienced with enough free time in the next months. Please only apply if you are also willing to bugfix and develop future functions. A basic understanding of the German language is a plus. Please give us an overview of your former projects with screenshots. If we are interested in you we will send you a documentation with the desired functions. Please read it carefully, as we will ask on the interview for your time estimates. If anything is unclear please feel free to ask.
