Dear Ms/Mr,
I have seen your demand for drafting some contracts which is in English language and in accordance with the law you request.
I want to handle this case. I am an legal consultant in a law office where I do draft contracts for clients everyday. So, I think that I have enough experiences to fully complete your request.
My suggested price is valuable and reasonable for you to consider. It will be great if you give me your price. I will think carefully about it for achieving the best price for us.
I hope that we will reach a good deal for both of us. Thank you very much.
Your faithfully.
