Dear Sir,
My name is Yasir & your project recruiter Loreley invited me to place a bid on your project, as our expertise/skills match with your project requirements.
I have read Project Description but really need more detailed requirements or can you list down all the high level features in a document to estimate it precisely, because based on the project description, it is hard for me to give you any estimate.
You may ignore the bid & once requirements are finalized, I will then give you firm bid.
Look forward to hearing from you.
Regards,
YK
