Dear Sir,
I have read your project description & discussed with my technical team lead too. My team said that it should not take more than a month for this website project and cost can be around US $3,500 (Excluding Freelancer fee), so I am not sure why your budget is set to US $10,000 to US $20,000 or if we are not on the same page in terms of requirements understanding?
Please initiate the chat to finalize the contract details, estimate, payment terms etc. but just so you know, I am flexible in prices, as quality comes first for me and then prices.
Look forward to hearing from you & start further discussion thru' private chat.
Regards,
YK
