Can you imagine a going to your lawyer with a probelm.
They say they can take your case.
Then they go to a forum saying, "I don't know what I'm doing!"
That is exactly what a lot of people here are doing.
Why don't you learn about marketing and then offer marketing services?
I know, I know... that makes more sense, but yet most won't.
Also, if you are not a consultant, don't call yourself one.
"I sell SEO, I am a consultant." NO! That doesn't make you a consultant.
You are a service provider. You may be a SEO company, but you are not a consultant.
Same goes for web design, and whatever other services you are selling.
