If I were in your position, I'd buy a decent printer, envelopes, and stamps. I'd then start searching for free addresses to market your services too (driving for dollars, FSBO, talk to your title office avout absentee addresses, and For Rents on Craigslist). Once I found those free leads, I'd set up marketing campaigns and hope to find a truly motivated seller.
You will also need to start networking with cash buyers; utilize all the free resources you can (call for rent signs, contact other wholesalers, work with your title office, join REIA groups, network).
Running a wholesale business takes time, money, and talent. It sometimes takes months and thousands of dollars to get your first deal completed. Here are some important questions to ask yourself:
Do you have resources to continue to pay for marketing?
Are you talented enough to be creative with your marketing to get leads to call?
Do you have the ability to close deals with sellers at a heavy enough discount?
Do you have the time to invest into searching for a deal?
Do you have the motivation to invest the time and money needed to be successful in this hard business?
