[MOD-REQUEST] volleyball

hi,
This is my volleyball-map:

I made this map 3or4 months ago, but this map wasn´t so nice like yet
I hosted it with the sportsmod (thx to Rajh), but there are some bugs
I hope, someone is able to make a new "volley"-MOD

here are the bugs:

Explainition:
blue tees= respawn-points of the blue team
red tees = respawn-points of the red team
blue footballs: if blue "shoot" at these blue footballs, blue team scores
red footballs: if red shoot at these red footballs, red scores

the black line should be the "outline"
the serve should change every point (here only blue has the serve)
bug2(look at the picture): if blue shots the ball at the net of redteam, blue scores (many "kiddys" use this bug -.-)
bug3: the ball "double-jumps" on the net

so, I think thats all.
I hope, somebody helps me

(i made this picture with paint *crap*, so you can see every pixel )

THX to Landil for his nice tilesets "pirates_main" and "pirates_doodads"
and THX to Sub Focus for his nice Parasols, Palms and Beachballs
I´ll put this map into this forum, when this map is "finished"
If you need the map, pls send a Private Message  or ask here in this thread
