Hello Sir,
Hope you are doing well.
We have read the details of your project and as being a team of highly skilled professionals having a vast experience in programming and coding specifically in the languages like C++ and C# ,can most certainly do the job for you.
However, we have a few queries before we proceed further.
-what is the time frame you want the project to be completed in?
-what is the basic aim of building the portal i.e selling online or just promotion of the business?
Looking forward to working with you and developing a relationship based on professionalism and trust.
Regards,
