Logo Creation for two brands

I need two logos created. Both need to be in a similar theme with pastel colours.

The logos are for the below companies:

1. Shimmer & Slime. A business that is making and selling slime for children, as well as squishies. This is a company run by children for children. There are three kids making this. One boy (8 years old). Two girls (5 years old and 4 years old). Perhaps some form of rainbow in the logo (and the girls love unicorns).
2. That's Sweet. This is a company that provide candy cart services for weddings and events. Colourful sweets on a cart that is decorated in the theme of a wedding or party. The company will also be selling sweets & candy online.

We need the logos asap, but they need to be of a high standard to ensure we stand out from the start.
