I had the same problem on my lvl 30, except i wanted to make staff enchant II (which requires potions level 20) for the burnt staff.

What I did was go to Port Royal (easiest for potions that only need aliigator, crab, and scorpion ingredients) and made swift foots 1, 2 and 3 over and over, selling them whenever i had 5 of each. I went from potions level 9 to 20 in about three days total, and got a fair amount of gold from selling the potions.

I would also recommend making some of ther other potions too, like Clap O' Thunder. It doesn't earn rep as fast as the swift foots did (IMO), but it does come in handy.
