Dear Sir,
I have read your project description & discussed with my technical team lead too. Actually to give you high quality solution, we have better offer but based on all the features, you explained, our estimate is coming higher than US $1,500, so not sure if you can be flexible in your budget.
This initial message is just to confirm you that we can do this project, so 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
