Hello,
It's kind of error solving task so we can go on hourly basis.
Initially it would not be feasible to define amount of time required so solve errors
in any third party script as we would not have idea about the how coding is done also.
I have gone through project description, but I would like to discuss to clear my understanding of requirements.
Please PM me so we can discuss the requirement in more details, clear doubts and move ahead.i can share more some latest design sample.
Kind Regards,
Champian
