dropshipping works if you are creating a niche site that wants to expand it offerings , im guessing your wedding planning service is being aimed at a local market too ?
that would give you a perfect way to get your local market seeing you as a "local market leader" when it comes to all things weddings when they search online ..... you could offer a custom made service if you can find a good jewellery maker to work with too , the possibilities are endless for expanding a niche in that way , you could even offer books ;o) diaries and notebooks lol ....
Think of it as a marketing exercise , cherry pick little bits and pieces from wherever you can to give your service something different to everyone else and you are onto a winner , i used to subsidise my floristry work in the same way , offering jewellery services from businesses i had "met" along the way , that i knew and worked with regularly .... develop a relationship with potential suppliers and you would be surprised at what they may be able to suggest and or consider getting in ;o) to help you grow your businesss and theirs , you dont get to do that with affiliate earnings :o) , the better relationships you can forge with suppliers and other businesses on your way the better chance you have of being able to fill your customers requirements in a way no one else can
