Hello,
Great example sites, let's make yours even better.
I've worked on a few "live" sites similar to the one
you want built. If you where open to it, I think you
could get it done much faster by switching to a
MEAN stack (AngularJS, Mongodb, Express, Node).
It's invented for this type of thing.
You would be able to send and receive data in real
time. This means live updates, twitter feeds, and
even payments.
I think your members would enjoy the interactivity and
you would be able to manage it with much less difficulty.
I don't have a lot of reviews (yet!), but I do have a lot of
experience in this area. Message me at any time and I
can have this up and running for you very quickly. Thanks,
and best of luck.
cheers,
