Skip rows in bulk insert

I am using bulk insert to upload .CSV file to SQL Server.
I want to skip 1st three rows of .CSV file.
I am using FIRSTROW = 4 in bulk insert but it is giving me error.
I think FIRSTROW works only if there are same no. of columns
First three rows are not having 4 columns,there are just like title.
Is there any solution for this.Plz give in details.
CSV file looks like -

STOCK EXCHANGE
----------------------------
NO. OF ORDERS : 100
ORDER_NO, BROK_ID, BRANCH, USR_ID
2.00707, 10412, 31, 18274
2.00707, 10412, 31, 18274
2.00707, 7536, 5, 4278
2.00707, 7536, 5, 4278
