Hello Sir,
Hope this finds you well.
I am assure that you might have got a lots of bids for you project and if I say I can do this project then it will not work at all. I might have to show you my skills, my knowledge and have to provide you something special which can assure you that I am the right candidate for this project. I need only one discussion with you regarding this project.
Hope to receive favorable response soon.
Have a nice and productive day ahead.
Thanks with best regards,
