VBA for Lucky draw displaying numbers

I'm trying to write a simple VBA for a Lucky draw for a charity event here. Unfortunately I've misjudged my VBA knowledge a bit, I'm rusty...

My aim:
Have one cell quickly display a random number within a predefined range of numbers and stop this with a stop button.

Sofar I have this code:

Sub startTimer()
Application.OnTime Now + TimeValue("00:00:01"), "Increment_count"
End Sub

Sub Increment_count()
Range("A3").Value = Range("A3") + 1
startTimer
End Sub

Sub StopTimer()
Application.OnTime Now + TimeValue("00:00:01"), "Increment_count", Schedule:=False
End Sub

The problem now is:
1. I need to limit the range as specified in 2 cells (from and to range). (now it just runs up indefinitely)
It should keep running till I click the stop button.
2. I would prefer the numbers to be displayed randomly
3. The change in numbers is far too slow (1 per second)

Any help will be greatly appreciated,
Tnx

Hi Vicho,

Works like a jem, Thank you so much.
We're going to project this during the event.
