Don't waste your time. Call an expert. Given my deep knowledge about Yii framework and PHP in general I am able to solve a lot of problems in very short time.
Book the "PHP and Yii Competence Call" and save your developers valuable time. Reduce the time spent on trial-and-error, better spend it on getting things done.
