Coder Needed to Create Email Import Scripts

Need a developer to create PHP scripts that will import our customers names and emails into [login to view URL] automatically using their API interface [login to view URL] There are three sources/databases where the email addresses are collected on our site. 1-Joomla/Virtuemart, 2-Kayako support suite, 3-Our flash shopping cart database. I would like such scripts to run on a scheduled basis possibly via CRONtabs. Such script should have a GUI so I can later choose which subscriber group at mynewsletterbuilder I'd like each of the three email sources to be imported into. Im looking for an individual who is interested in "On-going" work as I have a few other similar joomla based jobs I'd like done after this one and would like to use the same coder.
