Please do enough of homework before approaching your clients.
Know your client, understand their business nature, learn what they are doing, study their objective.
They have website, they have Facebook page for you to read.
Please, do it.
Don't ask simple yet silly questions which make client know you didn't do your homework at all.
If the client provide the 'juice' for you, you are just helping to materialize and assisting in the execution part.
Why not, your profit I take 30% of it?
How was that?
Do your homework!!!
