You may find that Pay Per Clicks can be a bit of bad and good…
Overture produces results with good traffic volume but is costly as hell so the traffic from them aint what it use to be unless you can afford $5 per CT and more.
Google adwords never worked well for me. Spent all my time reworking ad copy to ensure that they didn’t pull me for low CT’s.
Findwhat was my favorite alternative as I always did okay with them although conversion were not as high as Overture znd traffic count wasnt super high.
GoClick does quite well but wont produce a ton of traffic.
ePilot made me money, but only because I landed the odd whale there, otherwise I would have lost money with them.
The rest are garbage from what I can tell and I’ve tried alot of them.
SEO is probably the best bet but you need to be pretty damn good at it to get the high placements in this competitive business.
Offline stuff hasnt really worked for me although I havent tried TV advertising… yet 
That’s my 2 cents worth.
