Fin Box Broken

Hi all,
I broke the fin off my surfboard whilst surfing in Wales about a month ago... Unfortunately the fin box has also been damaged and is slightly out of place, with one plug remaining in place with some of the fin left inside.
I have only started recently getting into surfing, and I'd like to attempt to fix this at home, however I do know that going to a repairs shop would be the safest bet. How should I go around fixing this? Will I need 3 new fins, a new fin box or what?
They are M-3 FCS fins and I will need the board fixed within two weeks
The board is a 7'6 minimal bilbo torpedo
I would appreciate any help immensely! And apologies for my lack of knowledge
