Help In Retreiving Multiple HeadCount

Hi all
I have the following table schema and their details as follows:

Code Block
CREATE TABLE #Tbl_Project
(
ID varchar(40),
Name varchar(50)
)
GO
CREATE TABLE #Tbl_User_Project
(
ID int,
ProjectID varchar(40),
Role varchar(20)
)
GO
INSERT INTO #Tbl_Project VALUES('PRJ1','Project 1')
INSERT INTO #Tbl_Project VALUES('PRJ2','Project 2')
INSERT INTO #Tbl_Project VALUES('PRJ3','Project 3')
GO
INSERT INTO #Tbl_User_Project VALUES(1,'PRJ1','PM')
INSERT INTO #Tbl_User_Project VALUES(2,'PRJ1','TL')
INSERT INTO #Tbl_User_Project VALUES(3,'PRJ1','TM')
INSERT INTO #Tbl_User_Project VALUES(4,'PRJ2','PM')
INSERT INTO #Tbl_User_Project VALUES(5,'PRJ2','TL')
INSERT INTO #Tbl_User_Project VALUES(6,'PRJ3','PM')
INSERT INTO #Tbl_User_Project VALUES(7,'PRJ3','TL')
INSERT INTO #Tbl_User_Project VALUES(8,'PRJ3','TL')
GO
--Required Output
--ProjectID ProjectName PM:TL:TM Ratio HeadCount
--PRJ1 Project 1 1:1:1 3
--PRJ2 Project 2 1:0:1 2
--PRJ3 Project 3 1:0:2 3
DROP TABLE #Tbl_Project,#Tbl_User_Project

This is just sample of the values. The ratio obtained should be as follows:
Assuming for a Project 1 there are 2 - PM's , 6-TL's , 15 - TM's then the ratio should be 1:3:7.5 . So please help me in this regard.
