Dear Mr. Balasubramanian, I think you have a large task ahead of you, especially as it is only a two layer board. Also think the 6db margin is a little harsh. A 3 db would be enough I'm sure.
Anyway I would be willing to review your schematic and board layout and make recommendations if required. I charge $750 U.S D. a day. I'm sure this would only take about 1 day to review. I need a deposit of 50% to proceed. I could arrange for testing here in Canada to verify the design, this of course would cost more money. Please let me know if you wish to proceed.
