Hi Colby,
I wouldn't consider myself a veteran but I am active in wholesaling. I started just like you and have lots of crafty inexpensive tips. The cheapest way of marketing is
1) Word of mouth!!!!! This kind of goes along with business cards at Vista Print you can probably get around what??? 250 for $25. On the front I always put a message that lets everyone know I buy houses. On the other side I write down that I pay for referrals on houses. Why??? Well...tell everyone that you buy houses...the grocery store clerk, servers at restaurants, contractors, I say this "I'm expanding my business and a lot of my business comes from referrals from people I run into. I'm always happy to pay people who send me business, once I buy a house" This works with anyone who is interested in making extra money.
2) Driving for dollars, look for houses that look like no one lives there.(there should be plenty of info on subject on BP.
3) Letters and Post cards. At this moment I spend $150 on both. I send yellow letters 100 which I get 100 stamps for .49 cents (foreverstamps) I also buy 300 post cards the template I ordered from vista print and its around $99 plust tax. Yellow letters Walmart sells like a 3 pack and white envelops at the 99 cent store...walmart also has 40 envelopes for like 88c.
AS FAR as learning how to wholesale...read a bit on bigger pockets to get the general idea and mechanics. Once you have a good general understanding..the next best thing to shorten the growth curve is partner up with people. Either here on BP or in local networking groups...and join lots of buyers list..this will put you in circulation for when other networking groups are meeting. Find a person and bring them a lead not a contract..let them help you with that and the negotiation. I've splitted a bunch of deals with people as well as co-wholesaling with other investors in the area. If you end up taking a class...please don't take it from a GURU...take it from someone who is active in the Houston area.
Lastly...keep reaching out to people.
