Wix store - add customization options to products

I am looking for a talented freelancer to help me with adding customization options to my Wix store. I have physical products that I would like to add custom options to. I want to sell cakes on my website with the ability to customise with multiple options. These custom options could include add-ons such as macarons, birthday candles, or personalised chocolate plaques. The customer must be able to select multiple of these options via a check box which will add to the total price of the product. I would like to add customization options to 1-5 products in my store (but if you can get one product done, I can copy and use the template for the other products) At the moment I'm limited to the variants function in the wix store. If you feel like you have the skills to help me with this, please get in touch!
