Hi there - I'm Aly,
I've seen your post and I'm interested. I've had much experience in Microsoft .Net technology stack and fortunately, MVC is one of my preferred. I also have few Angular.Js experience. I understand you need to have a website that works with Paypal and MongoDB, and that you have a present website. However, it's not clear to me what is it precisely are you trying to achieve. Am I going to be adding new components to the present website? or should we build a new one? Also, I'd like to discuss your choice of picking MongoDB rather than Microsoft's SQL Server. Once we have shared understanding of the detailed requirements, we can then discuss milestone structure and deadlines. I'd like to know more about your expectations for this project. Don't hesitate to contact me so we can talk further.
Sincerely,
Aly Elhaddad
