SQL Server Reports Required

I am looking to create several SQL reports (sales reports, staff sales / performance reports, total sales etc).

Some reports are simple, some are more complicated and I would be willing to provide you with a sample database and information on what reports I require.

A background to my project: I have a .Net winforms application that uses a MS Sql Server 2008 and/or 2012 database. Its designed for CRM / ticketing / POS software I have designed. I am a Windows C# developer of 15 years with very limited SQL coding skills which is why I am contacting you. I have created some basic reports but need someone like you with advanced skills.

The software uses Teleric Reporting (if you can design the reports using Teleric then this would be great!).

I can provide you with a sample database.

The reports I would like:

(Over different times i.e. Year, Monthly, Weekly, Daily)

[1] Employee Performance Report
Total Tickets Completed by each staff member for different time periods
Total Tickets Opened by each employee
Total Tickets Closed by each employee
Total Tickets Currently Open by each employee
Total Revenue for each ticket completed by each employee

[2] Sales Report
Total Sales
Most Popular Sale Items


[3] Products and Stock Report
Items In Stock
Items Out of Stock
Items Low Stock
Total Purchase Value of all Items in stock
Total Retail Value of all Items in stock
Items Purchase Price, Retail Price, % Markup

I will have more reports in the future but this is a good start.

If you need further information please let me know. I can provide you with sql scripts to create the database.
