I haven't time to go through it in detail, and i don't know the company, but the structure seems fine.
a couple of questions: assuming you're using this for forecasting, it doesn't need to go back to 2001, and don't you need to forecast beyond 2008, assuming you want to drive a valuation from it? You wouldn't really take a fundamental valuation off a 2008 EPS forecast.
and - bearing in mind I don't iknow what the company does, or what you want the model for - it's a decent financial model but you need some more drivers so you can flex the variables, particularly at the revenue line. eg lets assume staffline do staff recruitment. I'd want to see 'number of staff placed x average revenue per staff placement' or whatever is most appropriate as a minimum so I could easily flex the assumptions, eg what happens if they maintain their fees, but numbers go down, etc. You can then do sensitivity analysis to different scenarios, You can't do that if you just model revenue as 20% more than last year's revenue.
Shouldn't the mentor at your internship be reviewing this for you?
