Logo Designer — Match Existing Brand for New Kids Sports Program

We run two kids' enrichment programs in Hawaii. One is Keiki Coders (coding), the other is Keiki Athletes (multi-sport for elementary kids). We already have a logo and full brand we love for Keiki Coders — colors, typography, mascot, the whole feel.
We need a logo for Keiki Athletes that lives in the same family. Not a copy — a sibling. Same playful, high-quality energy, similar logo size/weight, coordinated colors. It should be athletics-themed — could be a turtle (like Coders) or another animal that fits a kids' sports brand.
What you'll get from us:

Keiki Coders logo (to match against): ----------
Keiki brand toolkit (colors, fonts, the works): ----------
Our temporary Keiki Athletes logo for reference (shared after we connect)
Fonts and brand items are already in Canva

What we need:

3–4 distinct logo concepts to choose from
One round of revisions on the concept we pick
Final logo in vector (AI/SVG) plus PNG exports (full color, white, black)
Horizontal and stacked/icon versions
A simple one-page sheet showing colors and fonts used

To apply, do these 3 things (applications missing any will be skipped):

Link your portfolio — we want to see logos you've designed, not general graphics. If you don't have a logo portfolio, do a quick rough mockup sketch of how you'd approach an athletics-themed mascot logo and send a photo or image of it.
In one or two sentences, tell us your approach to designing a logo that matches an existing brand family.
Start your reply with the word "keiki" so we know you read this.
