You have several things to consider when planning your wedding. You must take each topic seriously, and it is often wise to hire someone to help you. A wedding planner can take care of lot of this, and you can do many of these things yourself if you want.
The venue you have chosen must be large enough for your guests, fit your decorations, and have enough parking. You can pick a ceremony and reception location that are separate, or you can get one location that does both for you. Ask them if they can provide food, and see if they have a DJ or band to use. Ask them if they have tables and chairs, and make your arrangements based on their answers.
You need a caterer who can plan the menu, let you taste it in advance, and make it on site. The caterer that does everything for you takes a lot off your plate, and they should be willing to make vegetarian, vegan, and allergy friendly options. You can get a buffet, sit down meal, or something in between.
The bar could be a part of this process, or you can hire someone separate for the bar. The bar might be a cash bar, open bar, or dry bar depending on what you prefer.
Anyone can officiate your wedding provided they sing your wedding certificate, and you need someone who is prepared to show up to the rehearsal, give you advice about the wedding, handle the ceremony, and possibly show up to the reception.
The photographer must be prepared to stay at your wedding for a very long time. They take wedding party pictures before anything starts, and they take pictures of the entire event. The photographer can do engagement pictures for you, and they can develop everything, make an album, and help you create a website for your wedding pictures. The pictures should be saved digitally, and the pictures should be chosen based on what you like best.
You need a car that will take you from the ceremony to the reception, or from your reception to the airport. You might be going off on your honeymoon that second, and it is important for you to have that car lined up before the reception begins. The driver should pick you up, take you where you want, and you can pay for it all in advance.
Your wedding is a complex affair that you should plan well in advance. You can get everything done with relative ease, but you need to check off everything on the list with your spouse’s help before you plan to walk the aisle.
