in that case ppl who have got published work can always send links.... this is as good as writing a sample if "quality of work" is a concern..!!
Dear Friend ,
I understand your point , but you will visit the doctor only when you know he is reputed.
How many times you have visited a doctor or a mechanic when you do not even know if they are capable of curing or rectifying your problem.
So that free sample will justify the capability of the article writer , how suited he or she is for the project !
Any more queries, feel free to shoot bro !
Thanks
