Greetings,
I have read Project Description & seen the attached image to understand the issues, as we need to review existing code too, so it will take around 20 Man-Hours but we are flexible and can negotiate the cost.
So, please drop me a message thru' PMB to start further discussion about your project, as we cannot write much on this initial message bard due to limitation of characters.
Look forward to hearing from you.
Regards,
YK
