Help with mailing campaign

[LiDairious H.]

Good day, I have been actively posting bandit signs to bring in most of my motivated sellers. However, with the competition popping up in my market (Cincinnati ohio/northern ky). I need to add to my marketing strategy to find more sellers. Can anyone recommend the best form of mailing campaign marketing? Should I use yellow letters or postcards? Should I market to specific areas (zip codes), absentee owners, attorneys or what? What is working for some of you? Also, are you using companies to do the work, or are you sending the mailings out by hand? Are you using a list source to get leads, or are you using the MLS? Thank you for your assistance.
