Follow nghiabk92´s shoutout to make a beta today. People wont complain and start testing.
I dont think you are overexperienced and in conclusion to this there will be bugs etc.
Doing a beta would be the best step you can do at the moment. Let people test everything. They will have something to do and you won´t fail on the grand final.
+ Your signature says the grand opening is on Wednesday the 13rd of January, 2k16.
Hope you got a good website tho.
I like your idea and hope you wont dissapoint us
Good luck!
