A good business is built on trust and honesty...empires are built on honesty. As a research writer, to ensure trust between my clients and I, I provide a contract which is in accordance to the constitution of Kenya, by which both parties must sign and is admissible in the court of law should either party fail to deliver on what is agreed upon. This is how I have been able to build a trust with my clients either new or old for the last 3 years. However, for those with doubts, I understand your fears if you are new in this kind of business.
