How to kindly decline help

I would just be honest and say that you appreciate the offers, but that you really want them to enjoy the day without having to play a professional role. If they keep pushing, explain why friendors aren't a good idea, and to just be supportive through the planning process.

I would emphasize that you highly appreciate that they want to be involved in the wedding, but you have everything covered. Tell them if you need anything you know they are there to help with whatever they can, and you will make sure to come to them with anything you may need.

If you already have your vendors booked, you can simply tell them you already have that covered and want your family and friends to relax and celebrate with you on the day of your wedding without having to worry about getting something done.

Honestly, I just tell them that I really appreciate their help, but I want them to enjoy the day as an honored guest and not have to worry about "working". My family was all about it when I told them I just want them to feel relaxed and pampered the day of and not have to worry about things. If they're still bugging you, give them work to do they can help you with (my mom took over the church decorations and linens).

"Oh, I already have a contract with a DOC/officiant/DJ/whatever. I'll be so glad that my family will be able to relax and just enjoy the day with me! How is your new grandchild/puppy/job? Do you have any pictures?"

My mom was the same way, she wanted to be my DOC, she wanted to officiate, she wanted to bake my cake. The only things she didn't push about was doing the photos, and she's a photographer!

I gave her a job, she took over center pieces, which what I was going to end up DIYing anyway. I know they're not going to be what I want, but it was worth it to me not to have to battle with my mom. And she is a creative person, she'll make them nice. Is there something small you could have your mom do? Can she shepherd your FG and RB?

When my mom said I didn't need a doc and that she could decorate and other people could help set up, I candidly asked her if she would like to be decorating and waiting for deliveries, or rather if she would enjoy getting ready with me while I had my hair and makeup done. When she heard it that way and considered it she agreed we needed a doc.
