web site / DB enhancements

We have several existing websites that interact with external and internal data sources (data files dropped into a local dir ready for processing or obtained via XML or information obtained from other localhost DB's ). The current developers, whilst their work is good, lack consistent communication and the ability to deliver sub-projects on time and this has caused hardship. Most of the work revolves around scripts that correctly import data to selected BS's and then present this data to Users within a Joomla (1.0.x) framework. Acknowledging the limits joomla has with registered users, some scripts have a existing criteria to allow only certain data or menu items to be presented to the logged in user and this is working well. This does not involve Joomla core. There are a number of scripts that need to be fine tuned or finished off and on an ongoing basis further development to occur. For the right freelancer it would mean an assurance of ongoing work each month. Due to the variable and ongoing nature of the work involved, it is probably best to quote an hourly rate. Of extreme importance, aside from the technical ability to actually carry out the work is: - a good command of the English language - be available via MSN or similar for reasonable portion of the day between 9am and 7pm Australian time to assist with development. - quote delivery time on sub-projects and delivery these on time.
