How Do You Usually Bring In New Leads for Your Business?

[lukwiso]

I'm curious how people in different industries go about finding new leads. Do you mostly run ads, rely on word-of-mouth, attend events, use social media, or something else? I figure every niche has its own way of doing things, so I'd love to hear a mix of ideas.
For me, I've been experimenting with a few options this past year. One that worked well was BestMovingLeadsProviders.com, which is geared toward the moving industry. The leads I got were pretty solid, and I noticed both the number and quality of inquiries improved quite a bit.
Has anyone else here tried using a third-party lead provider? Did it end up being worth it, or did you find other strategies that delivered better results?
