I’m not sure where you’re located, I’m sure you can find a good baker in your area-hopefully we can guide you if we know your area.
Some tips if you decide to try yourself:
UV cake stand with glowing cupcakes:

Frosting:

You can make the frosting ‘glow’ the link I sent was a jello method but I’ve seen it done with turmeric as well.
If you google ‘glowing’ cake/buttercream you’ll get some ideas. The second link was to a homemade stand I saw here on CD, I imagine it was covered with some paper (or even painted).
Depending on the design you want you could use some led lights or even glow sticks.
