If you would contact 100 business owners and ask them the following:
'Hi, I have made something special for your website. Can I send you a demo link so you can have a look when it suits you?'
How many business owners do you think will let you send a demo link?
There is no right or wrong answer, btw. I rather have you come up with numbers you think are realistic instead of me telling you.
Before choosing one of the options, make sure you write down this number!
