Agent, I usually keep business card with me and give those out. All of my business is by word of mouth. When business is slow for me I usually bring something into the office or send something with my hubby. That usually gets it going again.
I checked all of this info before I moved from Cobb County and they did require that you have a seperate kitchen and sinks, etc., also, you have to follow the association rules of the housing community, most say no commercial kitchen (it COULD create too much traffic in the area). I also tried finding a kitchen, which turned out to be impossible, I had no luck. Most people find a church that they can use, but it can not interfere with the church's use. I found that it was too much trouble for the amount that I was doing. I works out fine, me baking in my kitchen. When I get more volume and no longer have the space, then I will have to get a seperate space.
