Find Text In Column, Copy Next Row And Paste In New Sheet

Essentially, I have 2 Sheets:
"SheetWSS" = data to be copied
"SheetWSD" = destination of copied data.

Below is a sample of the data in "SheetWSS"
----------A------------------------B-------------------------C
1------Trade ID -------Description---------System no.
2--------579----------------Loan ---------------------- 7
3--------580----------------Deposit---------------------22
4--------702----------------Deposit--------------------- 11
5--------703----------------Loan ----------------------- 58
6--------732 ---------------Loan------------------------66
7--------733----------------Deposit-------------------- 99
etc...(no more than 10000)

Now, an explanation of the data:

1) I work for a small bank (CORP) that takes deposits and gives loan.

2) CORP books these trades using only system no. 7 and 11; other system nos. belong to customers.

3) When a single trade is booked, the 2 sides of the transaction is recorded (by Trade IDs) . E.g rows 2 and 3 relates to one trade. So if CORP loans money with system no.7 to CUSTB, who uses system no.22, it shows for CORP a loan and for CUSTB, a deposit.

4) Everyday, the data in "SheetWSS" is updated with a different number of rows from previous, but the number of columns remain the same.

So, here's what i'ld like the macro to do:
1) Go into Column C, find system no.7 and 11.
2) For each 7 and 11 found, Copy the next row . So if for e.g, system no.11 was found in C4, i want the ENTIRE ROW 5 to be copied.
3) Paste the entire next row in "SheetWSD" until we have a list of all opposing sides of the same transactions initiated by CORP.
