Recently, I have had a couple of clients want to start projects that could have been done years ago but they decided against it.
When they said “no” in the past what they really meant was “not now”. While the offer didn’t change, the thing that did change was the timing. For whatever reason, they (or their business) are in a different situation then they were previously. If you give up on them upon hearing “no” you will most likely lose the opportunity when the situation changes and they are ready.
This does NOT mean to keep harassing people even after they say no. Rather, let it go, do occasional follow up and when they are ready, they will let you know.
Remember, sometimes no means not now
Have a great day!
