Salesforce ISV Partner needing immediate help manipulating force.com AppExchange program.

Goal is to have Salesforce Dashboards Customized.  Client is using Dashboards and Reports for BI on large database.  Client is a salesforce ISV partner.

The native salesforce dashboards are not providing needed flexibility in defining date ranges because of limitations on the supporting report infrastructure.

Visualizations need to provide:
1.  Non Standard Date Based Visualizations Such as "Same Day of Week Year 1 vs. Year 2. Chart visualizations.
2.  Visualizations that persist by user by date ranges user selects.

Client has spent time on solutions and would be willing to present current status of efforts.

Client is submitting RFP because of a time deliverable and looking for very specific development by developers that have expertise in DeveloperForce, Salesforce Report, Dashboards, Object Creation, Visual Force, and APEX programming and a detailed knowledge of Master Child Relationships.
