Downloadable Excel Database

Hi,
Can anyone recommend a downloadable Excel database. I am not looking for anything ultra sophisticated as users will be Excel novices. The environment it will work within is a medium sized engineering company and ideally will encompass quotations, workshop orders, sales/purchse ledgers and invoicing. I look forward to any replies
Regards
Keith

Dont know of any downloadable but it is easy enough to make one. So let me know what sort of thing you are looking for in detail and I will pull a quick template together for you if you like and attach it.
