Greetings,
What do you think about using an already proved platform, that is in continuing development, in it's 7th release. Has an amazing community and also has an add-on engine?
This could be implemented in a few weeks, and i can do some live sessions to guarantee you that this implementation would be a success.
If you have any further questions, just PM me and we can discuss about an whole budget with milestones of implementation, sessions and a month of Go-live for free.
There is no catch, is based an Open Source platform ;)
