Design a board game playing surface with follow on work

board game !!! Pit Stop Pursuit

Kids Board Game called Pit Stop Pursuit for the under 12 year old and over 5 year old crowd with a focus on race cars / grand prix / nascar / F1, etc... open to various race car concepts... Please ask questions along the way!! I'm collaborative and open to feedback and providing direction :)

Board game surface - 20 inches x 20 inches...
the game has 100 playing spaces - similar to the chutes and ladder game, but it has various other elements... I'm looking for a game board design that can fit on a 20" x 20" surface with 100 game spaces - not including the starting line and winners circle. the game include various spaces that have play elements like crashes, pit stops, caution flags, etc... i can post a sample hand drawn prototype for context. Imagine a race track board game... that's the look and feel i am looking for.

In the image posted.. here are the basic rules / concept of the game...
2-4 players
race car theme ( name hasn't been finalized yet.... grand prix , race, etc type feel...)
Players start at space "0" before the 1...
Roll of a single die determines how ay spaces the race car moves...
Yellow spaces = yellow "caution" flags, where the player moves back on their next turn
Black spaces = "caution" flags for all players and everyone on the board (unless you are in the Pit Stop) moves backwards
Green Spaces = "Fuel Boost" and you move 2x your single die roll
Orange spaces = "Spinout" to the space indicated
"PIT" spaces = move any player (including yourself) to the PIT STOP and exit on next turn based on your 1-6 die roll
CRASH space = go back to the start
The finish line could have a 1-2-3 winners circle podium style artistry.. or something else...
Looking for the artistry of the board to resemble a race track for all ages... not a crazy sci-fi kind of image, but a traditional racing image - using either F1, NASCAR, or other traditional race car iconograohy

Significant follow on work for the winner!
