Excel accounting spreadsheet for a personal trainer

I require an excel spreadsheet where I can enter:

- Enter the pt package of sessions a client has brought
- The number of sessions I delivered for that particular client on a weekly bases
- How many sessions the client has remaining in their package

Then I would like to see:
- money earned per week minus expenses and tax
- amount of sessions sold in that month
- targets to hit for the following month
- graph or some visual representation of business growth (sales, profit etc)

I have had a go myself but it is not a slick as a I want. I need to be able to do my books weekly and quickly and see where my business is and look good.
