I am working with a different mind set, for me if client will earn a good amount, then I will earn reputation, I will get future references, also a long time business relationship and of course “money”. Whenever I start working for my clients, always prepare a report in which I can show to client that how much money he/she will gonna make within the time-frame and I actually do make money for them. This helps them to understand their ROI and also how much I will charge them for the work.
If client will get something by me then they will never think twice to give me money. Just be original, talk that make sense and help your client as much as you can, dont look at the money only.
This is what I am, and yeah I never lie, if I could not make you money, I won’t waste your money and priceless time :)
