Hey there,
I have been working full time with Laravel for the past few years, I have helped to build a big website from ground up, and was responsible for the management of the whole website infrastructure for 4 years.
I also have strong knowledge with databases, be it relational or non-relational.
While I'm really interested in your project, I need more information about the scope of the project. Your deadline here is really short, especially if the team is not yet in place.
I need to know how much you already have in place, if you have all servers fired up, if there are know issues with the current code, etc...
If you can talk more about it in the messages, I might be able to help you with this one.
Have a nice day.
