All the files need to get complete in W3C validation.
All the payments will get paid only in Freelancer and out side payments because we had a very bad experience in last week.
Payment mode should be 50% - 50%
First 50% will get paid after completion of 50% of work and pending 50% will get paid the 100% completion of the task.
Feel free to leave your doubts and messages in PM but before bid make sure i need this all 200PSD get complete
