Code To Delete Rows Based On User Input

I am using the following piece of code to delete unwanted rows from a worksheet:

Sub DeleteDates()

FinalRow = Cells(65536, 3).End(xlUp).Row
For i = FinalRow To 1 Step -1
If Cells(i, 3).Value Like "*2007*"
Cells(i, 1).EntireRow.Delete
End If

Next i

End Sub

What I am working with is a sheet of about 5000 customer appointments going back to the beginning of 2006. A have peiced together a lot of code to format it exactly as I want and to create a pivot table of what is remaining after the rubbish has been deleted.

However I am finding that I need to keep amending and re-running this bit of code, depending on the date range I want to look at. For example the code above will delete all appointments made in 2007.

My question is: is there a way that I could incorporate an input box, whereby excel asks the user for a start date and an end date and deletes any rows outwith that range?

Some important info: All of the dates are in column C, in the format mmm yyyy

I would only need to narrow down to a month - so for example mar 2008 - jun 2008
