I think that this conversation explains itself.
A lesson on reasonable pricing.

Gaurav says:

I didn't add him - he added me.

Kovich says:

Gaurav says:

Kovich says:
There are people who are native English speaking citizens with university degrees who don't charge anything near what you charge.

Gaurav says:

He then proceeded to send me some samples:

"I consider myself a big boating enthusiast. For the past 22 years of my life I haven’t let a single day pass by when I did not enjoy a boating trip in my backyard lake. Also, in these last 22 years I must have changed 12-15 different boats but being a hardcore boat lover, I was never bothered too much by the money that I spent. But whenever I got myself a new boat, I got a feeling that something wasn’t proper about it. I mean, the boat was all great and everything but something was just missing somewhere."
You decide - worth $15 or not?

Edit: Apparently this individual did not like this post:

you have no right to do that without my permission
its people like you who spil the net
anyways there no us eof giving you badwords
how can you just do that - if you dont want to pay dont pay - but why do you post my website details

I guess this thread is now a double lesson:
Reasonable Pricing and Professionalism.
