I have seen your job posting and I have to ask some questions. Please come over the chat so we can discuss things.
All the skills/experience will be discussed/revealed over the chat.
I need to know the technical details of this project.
It seems like an interesting project. I would like to discuss all the requirements with you, so I can mark the scope of this project. Please also note that final estimation will be provided once all the requirements will be revealed from your end. Hence, my cost of development & deadline solely depends on what you reveal (in detail). Looking forward to conduct an extensive chat with you.
