This would not be a difficult one. I do have 2 schedules I am working on before I could do this, so depending on how quick you need it, you may want someone else to do it. Otherwise I can do it - maybe a week???

I usually like to have more division games than outside so this is kind of what I could do:

Each team plays each team in their division 20 times (10 home/10 away- 3-3-4 series)
Each team plays each team in the league 3 times (0/3 or 3/0)
Each team plays each team in opposite league 3 time (0/3 or 3/0)

This breaks down to D60-N36-I48 2/3 of games in league 1/3 interleague Don't know if I like it with more interleague games than non division games.

Another option, but a slightly harder schedule to create would be something like this:

Each team plays each team in their div 21 times (12/9 or 9/12) OR (11/10 or 10/11) first option all 3 game series 2nd (3-4-4 or 3-3-4) four game series would be okay if you wanted a more balanced division series setup, because all non-division series are 2 games.
Each team plays each team in the league 4 times (2/2)
Each team plays each team in other league 2 times (2/0 or 0/2)

This equals 143 games so the one game will be to one team in the division making it as above but with one team being (12/10 or 10/12) for 22 games.

This comes out to D64-N48-I32 (112 in league - 32 Interleague)

Let me know you time frame and if any of these schedules would fit your need.
