Invitation How - To??

My fiance wants a small wedding and I wanted a big one. Since relationships are about compromise we decided that we would have a small wedding and a big reception. My first question is does anyone have any ideas on what I should put on the invitations for the people that are invited to just the reception? Second do you think it`s wrong for me to invite people to just the reception and not the wedding? I am at a loss here and I really need to get going seeing as my wedding date is May 31st. Any suggestions would be GREATLY appreciated!!!
