High quality Joomla! components by one of the original core developers of Joomla! and Mambo.
I contracted Emir to add conditional fields and a modal popup to confirm submission for his extension Ajax Register. The price was fair and the turn around time was unexpectedly short. Emir worked over the weekend to ensure delivery on time and even went so far as to help with updating the extension once work was completed. I can't recommend Emir highly enough. He is a man of his word and an excellent programmer. What more could you ask for in a developer?
