well then i can help! i'm west yorks too (leeds based)...
Saturdays - West Yorkshire League (line the step 7 prem, ref all other divs) & Yorkshire Amateur league (ref all divs)
Sundays - Combination and Triangle leagues (ref all divs)
Midweek - there's U23 and 19 youth leagues, the top divs operate with teams of 3 with no real restriction on who can ref or line (4s might line to 5s etc) with apppintments made on availability and club marks.
depending on where you are there might be local leagues (Huddersfield for example) but i dont know much about these.
you want any more info feel free to PM me
