We planned our wedding in 6 weeks. Dress from Oxfam which I customised, DH suit hired, button holes for about 10, white Hanson cab with floral decoration, registry office for 40-50, bouquet and one floral table setting, reception boat trip with canapés and champagne, reportage-style photographer, restaurant meal on the river, just for closest family and main friends (no cake), party at home in the evening, put up main family and friends, hotel stay for us at night before a flight the next morning for a week in Venice and Sorrento. Mother helped alter the dress, family paid for champagne and other drinks and helped make the food, sister sent traditional favours from abroad and a family friend paid for a hotel room for our wedding night. Cost us less than £4k, 25 years ago. People still talk about it.
You don't need hen and stag dos, churches (especially if you're not religious), 100s of guests, bridesmaids, groomsmen, flower girls, ring bearers, photographers ordering everyone about, cake, chocolate fountains, ice sculptures, photo booths, presents for other people, speeches, entertainment and all the rest of the bollocks. Make it personal to you both and don't compare with anyone else. Cancel what you can, only have people you like, ask for elements you really want as gifts, handmade things to personalise.
