Employee Hours Report With Multiple Rates And Categories

I am trying to create a a file that will serve as time log and dashboard report for consultants who work a maximum of two hours a day, with a strict(fixed) calendar schedule with multiple sessions. Some consultants may work one hour of a particular schedule on category A(Lead) and the second hour as category 2. How to create a sheet that sums the rates for all the categories worked on a given day without using a macro. Here is my sample data

Pay Categories:
Lead
Assistant
Admin

Pay Rates
Lead-$75/hr
Assistant - $40/hr
Admin - $20/hr

Sessions and Session Dates sample:
Session 1 - 10/8/2013 to 11/8/2013
Session 2 - 11/15/2013 to 12/15/2013
Session 3 - 01/06/2014 to 03/15/2014

*Note the dates will or should be listed in separate columns in order for them to be used for daily logging.

Employees (Sample)
Jane Doe
Jack Doe
John Doe

Desire goals of the report:
1. Daily log as employees work e.g if Jane Doe works on 10/8/2013 as a Lead and Assistant, ideally the data entry person should be able to enter these two values on one cell or pick the relevant value from a set list
2. The report would then match the value of the data in the cell for Jane Doe on 10/8/2013 with a table array with categories in one column and the pay rate in another, and return the appropriate pay value which can either be a sum of the two rates or the total hard coded into the cell.
3.Be able to create a dashboard report that would sum the totals by employee, month,sessions etc in a separate sheet vs other criteria such a budget etc.
