Microsoft Dynamics AX Customer Portal (SharePoint)

We tried to implement Microsoft Dynamics Customer Portal for our company. The project was assigned to a company (SP) but the solution they provided was a total out of the box SharePoint customer portal with minor Customization. However the proposed solution is not meeting our specific requirements or expectations and therefore we need an experienced service provider who have done similar projects before in order to implement a web based full-fledged customer portal which will be using Microsoft Dynamics AX database. briefly the project will include but limited to the followings: * New customer registration and password email retrieval. * Customer info with financial details/ balance info. * Invoice notification through SMS/Email. * Invoice searching multi-parameters - Basic + Advanced * AR notification through AX ( Alerts) Any interested Candidate..
