/me counts combat level digits
Anyway, there's no easy way about this. To earn anything (in both Runescape and life) you HAVE to devote at least 2 hours to it. Get your runecrafting to 44 and do nothing but make Natures for 10 levels (whereas personally I'd go insane after 2 runs

).
Woodcutting, really depends on what you cut and where. I've found that if there are less people in the patch as you then you get more done. So, expand your horizon, or raise it to around 75.
Fishing. I've gotta leave this one alone; no matter how hard I try I cannot force myself to sit in a fishing guild, day in and out...wouldn't wish it on my worst enemy.
If you're crunched for time then find something that's profitable in short and infrequent bursts, such as Treasure Trails and often times selling random junk in your bank.
Hey, it's how I manage to pull a ~750k a day 'salary' without doing diddly squat.
