Receptions costs and decorations

Hi there, I’m planing on having a wedding for ~50 guests. I’ve thought about having the ceremony at the Saskatoon Berry farm. I’m still not sure where to have the reception. I was thinking of having it in a community hall. How much would that normally cost for decorations and stuff? We wanted to cut down the costs by having a buffet style dinner. So I know I would have to cater food from some place. I’m not too picky about the decorations I really just want a white table cloth with some sort of pink cloth as well and maybe grey ribbon to tie the cutlery, have a center peice with some flowers. Not much else I can think of. I’m just a little bit overwhelmed about the reception part. Not sure what other decorations there should be??
