Only WHMCS expert / WHMCS developer (please read details)

Are you an expert in WHMCS? Did you create own templates / addons / modules / hooks / maybe even reverse engineer some parts of whmcs? Then you are the right guy for us! We are searching an advanced WHMCS expert / developer who is able to assist us with complicated problem such as: - Advanced Billing (Products have to have a product nr. / special variables etc. - we already solved it with a server module - but maybe there are more cleaner better ways) - Advanced TCPDF optimization (diffrent headers on diffrent pages, footer not on every page, etc.) - Advanced Template tuning ([login to view URL] - possibility to show some images only if a specific option has been selected in the backend) - etc. In the beginning the hours per week will be more... about 4 - 6 hrs... until whmcs is finialized... after that we will need support for our updates and future projects. We only accept biddings from people who actually read our details!
