I need to customize magento to do the following.

I need to use it as a back end for multiple websites on multiple domains.

The websites will be landing pages, all the rest happens in magento.

I also need to incorporate the idevaffiliate program and paypal pro and paypal standard payments while tracking the sales with the Idevaffiliate program.

can this be done?

I need an Expert that knows Magento- not someone that thinks they know Magento
