T-SQL (SS2K8) :: Add Total Row For Each Name

I have a field in a table which was VERY poorly designed, but that is a matter for another day. Long story short, this field contains, in most instances, where the sale was obtained, the sales man name, and a comment about the sale. A few records have garbage data in the field as the salesman name was not obtained so we want to attribute the info to 'unknown'Is it possible in SQL Server 2008 to write a query that will display the saleinfo for each salesman then a total row under the salesman? Something similar to this

Internet Mark .... statistics here
Phone Mark - applied for credit .... statistics here
Phone Mark - customer referral ..... statistics here
Marks Sales Totals .... statistics here
Next salesman data would go here

but break that down by each salesman and attribute the garbage data like 85623, albaca, racava to salesman 'Unknown'..This is garbage data that should suffice to achieve my desired end result. I know this is unable to occur with a simple select. I even tried a few CTE queries but couldn't get the syntax accurate due to saleinfo basically being a catch all column I was unsure of how to only extrapolate the data I needed

Create Table sales
(
saleid int
,saleinfo varchar(200)
,salestatus varchar(200)
)

Insert Into sales VALUES
(1, 'Phone Mark customer referral', 'Done'), (2, 'Phone Mark customer referral ', 'Done'), (3, 'Phone Mark - applied for credit', 'Holding Pattern')
,(4, 'Internet Mark', 'Done'), (5, 'Internet Mark', 'Holding Pattern'), (6, 'Internet Mark', 'Holding Pattern')
,(7, 'Phone Stan', 'Holding Pattern'), (8, 'Phone Stan', 'Done'), (9, 'Phone Stan', 'Holding Pattern')
,(10, 'Internet Stan - lives to far to drive', 'Done'), (11, 'Internet Stan', 'Done'), (12, 'Phone Vic', 'Done')
,(13, 'Phone Vic', 'Holding Pattern'), (14, '85623', 'Done'), (15, 'albaca', 'Done'), (16, 'racava', 'Done')
