Albano,
I think I would be able to help you. i speak Portuguese and if you need any help just ask. I personally use DeltaKits and so far I am happy with it.
The customers are out there, accross the street , next door, or accross town. They are businesses, individuals, or government agencies.
Do you know if anyone else is providing these services in your area? If so, try to find out how they are developing their customer base (sometimes learning from someone else's mistake costs a lot less.) Be creative. It is your business. If you would like to communicate in Portuguese I would be glad to help, but I don't think would appropriate to use the Forum.
