I've been doing some pretty extensive research on this as well, and had several of the same questions in regards to wholesaling.
Here are several things I found that seemed like they would be effective in at least finding a motivated seller:
1. Driving around and looking at beat up and ugly homes and literally knocking on the door to see if the owner may be interested in selling.
2. Social Media... Social media is the way of the future. Maybe open an account under your business name and start contacting and following people who could potentially be buyers or sellers and try your best to stay in contact with them.
3. Online Classifieds such as Craigslist or back page.com can be effective ways to place strategic ads that could draw buyers or sellers attention to you as a wholesaler.
4. The last effective method I have found is just in person networking. Get your name out there, tell your friends, family, bosses, co-workers, random guy at the gas station... It won't hurt, you never know.
Anyways, I hope this was helpful. I haven't began to wholesale yet, I plan to begin this summer so I can not vouch for any of this, these are just several things I have taken note of while researching. If anyone else has any other methods, please inform me!
