I accidently forgot to register a player, so here is my situation:
I have 5 courts
I have 25 contestants for mens doubles.  
Ideally I would like each player to get 9-13 games
Random opponents or grouped as long as not too much repetition.

Can this be done or am I going to have to kick someone???

Any help would be amazingly appreciated.

If it is easier I can push to 26 if that gives anybody ideas.

26 players, 5 courts and 13 rounds, with each player getting 10 games and 3 byes is something that might work.  For example:

  (25 10 v 26 12) (21  8 v 18 15) (24  5 v 22 16) ( 2 13 v  7  3) (11  1 v 19 23)  (20 14  9  4  6 17)
  (26 11 v 14 13) (22  9 v 19 16) (25  6 v 23 17) ( 3  1 v  8  4) (12  2 v 20 24)  (21 15 10  5  7 18)
  (14 12 v 15  1) (23 10 v 20 17) (26  7 v 24 18) ( 4  2 v  9  5) (13  3 v 21 25)  (22 16 11  6  8 19)
  (15 13 v 16  2) (24 11 v 21 18) (14  8 v 25 19) ( 5  3 v 10  6) ( 1  4 v 22 26)  (23 17 12  7  9 20)
  (16  1 v 17  3) (25 12 v 22 19) (15  9 v 26 20) ( 6  4 v 11  7) ( 2  5 v 23 14)  (24 18 13  8 10 21)
  (17  2 v 18  4) (26 13 v 23 20) (16 10 v 14 21) ( 7  5 v 12  8) ( 3  6 v 24 15)  (25 19  1  9 11 22)
  (18  3 v 19  5) (14  1 v 24 21) (17 11 v 15 22) ( 8  6 v 13  9) ( 4  7 v 25 16)  (26 20  2 10 12 23)
  (19  4 v 20  6) (15  2 v 25 22) (18 12 v 16 23) ( 9  7 v  1 10) ( 5  8 v 26 17)  (14 21  3 11 13 24)
  (20  5 v 21  7) (16  3 v 26 23) (19 13 v 17 24) (10  8 v  2 11) ( 6  9 v 14 18)  (15 22  4 12  1 25)
  (21  6 v 22  8) (17  4 v 14 24) (20  1 v 18 25) (11  9 v  3 12) ( 7 10 v 15 19)  (16 23  5 13  2 26)
  (22  7 v 23  9) (18  5 v 15 25) (21  2 v 19 26) (12 10 v  4 13) ( 8 11 v 16 20)  (17 24  6  1  3 14)
  (23  8 v 24 10) (19  6 v 16 26) (22  3 v 20 14) (13 11 v  5  1) ( 9 12 v 17 21)  (18 25  7  2  4 15)
  (24  9 v 25 11) (20  7 v 17 14) (23  4 v 21 15) ( 1 12 v  6  2) (10 13 v 18 22)  (19 26  8  3  5 16)

IAN!!!!!   You are a LEGEND.   Is there any chance you live close enough to me for me to buy you a beer??   
I had a friend volunteer to drop out, but your matrix actually allows me to bring in another buddy too instead.

I honestly cannot thank you enough!
