New member from nj/ny with questions on the first step

Hey all just getting started in the real estate wholesaling business.  Iv been in car sales for about 5 years and was always top dog at every dealership. Now that I'm no longer in car sales ( 2  years in the longshoremans union) Iv decided id like to start wholesaling. Simply because I feel my people and negotiating skills could easily be transformed and work to an extreme advantage in this field of the real estate market! First steps?? I had thoughts that "legitimizing" my business would be a smart first step. a.k.a. making a website, having business cards, getting a separate "business" phone/voicemail to answer prospective leads inquiring about properties or offering them. Would anyone suggest that this is the right direction to go before spending money on direct mailing campaigns/driving for dollars/running advertisements via craigslist or any other source? Any help and ANY suggestions are greatly appreciated! Thanks all for reading,  Nick
