As you research professionals in your area, make a list of decision-makers within the firm. Not everyone is on social platforms. To reach those folks, you can draft up a letter or personal note introducing yourself. Ask if they would have time for a coffee break or a quick phone call. Be sure to position how you can help each other. I do not believe you should make a blanked effort to buy a direct mail list and print off 5,000 post cards; instead, this is a very targeted list. It will cost you extraordinarily little to buy blank note cards and stamps. Do a few each week and hand write each one for a personal touch.
Growing a design business takes time and patience. It doesn’t happen overnight, and there are roadblocks along the way. Don’t give up on your dream. There will be days when you don’t feel like doing this stuff or question if it is working, but I tell you that these strategies work. Keep pushing forward and focus on the marketing and business efforts that make an impact long term.
