Jon and Stephs wedding

Hi everyone,  I'm not sure how this works, but basically we have found our perfect venue that we have booked, unfortunately now I am concerned we are not going to be able to afford it as I am studying at university, and although I work as much as I can I am struggling, so we would be over the moon with any help anyone can give, basically I dont want to give a long story, just an honest request for help. thank you to all in advance Jon & Steph
