Congratulation on making the leap! Don't sweat it. I got cussed out three times in a row on my first day. The next day...ZERO. Its hard because your pride is hurt, but if you look at it from the other side, I don't like strangers calling me either even though my number is totally public.
That being said, make that next call, or even have a friend pretend to be a disgruntled homeowner. I turned a conversation with a friend into that once when they asked me what wholesaling is. They came at me like I was a jackleg, but I was able to diffuse them and got them interested in helping me out by simply answering their questions.
Inexpensive ways are Driving, Google maps, county records search, Zillow, Redfin, MLS... I started by driving target area. Within 8 blocks of my home,(I drove for an hour after dropping my kids off at daycare 3 days in a row) I found 140 distressed properties. Of those, 10 are already on the Lis Pendens list in my county, and one popped up on day 3. Handwrite a note, and put it in the door or mailbox. Get some business cards (can easily get 500 for under $20) and give them out to everybody you meet. See if your local worship center will allow you to make an appeal, or add you to their business directory. Marketing is key, you have to be active, visible, and consistent. When I started my first business it took me a while to get comfortable with being on social media. After the first week of constant posts, I received more likes on one post than I had all the years I had been on social media. No converts, but it let me know that people are watching.
Just keep pushing and you will succeed. You clearly have a heart and morals, so use them to your advantage. I have yet to land my first deal as well (not a great closer LOL). I can check in on you to help keep you motivated if you want. I need some pushing as well!
