Do you recommend getting a lot of self-promotion items printed up for marketing our company?

Be very careful on what you have printed, you can spend too much of your hard earned cash on stuff that just looks cool and is not effective in bringing in money. My suggestion is start of with a really sharp looking business card and get your Web site online. These two items will be your number one shot for bringing in business. The next thing would be to work on low cost letterhead and envelopes so you can send out for proposals and sales information. Once your company starts to bring in money, then look at cooler ways to do your self-promotion and attract the bigger fish. Spend more money on mass mailing and cover more area with your dollar.
