Need teacher to check GRE Wrinting.

[tigrantsat]

Hello,

Do you know some web sites where I can uppload my GRE writing and someone can check it (for payment, of course)? Due to complexity and specific of test, not only spelling and grammar should be checked, but structure, logic, etc.
I think of a system where I can uppload typed matheril and get some respond. I plan to use some online checking systems (like grammarly), but in any case professional checking is better.

I just started preparing for GRE and will appreciate any help.
Thanks.
