Dear Customer,
First of all, I hope everything is going as planned.
That being said, I declare that I can meet all your requirements.
I would complete the project using .NET Framework 4 or .NET Core 2 as you desire.
The proposal consists of the construction of a web app with the same functionalities with a responsive layout, Web & Mobile ready, in three days of time.
If, for any reason, I can not complete the project in this time frame, I am more than happy to refund the full amount and deliver the project anyway, being that, it only applies if you are available to answer my questions when necessary in a time short so that it can be a continuous work.
I sent the proposal in three phases:
1 - Acceptance of the proposal after chat/call conversation;
2 - Presentation of several options with different layouts of your choice and acceptance of it;
3 - Delivery of the project;
Feel free to change the stages of the project if you have an idea that best applies.
Kind regards,
Igor F. Machado
