Please help me to create funky character artwork for my business in children's play!

BabbleStreet (Mobile softplay & Event creché Hire) Tagline: Meet,Learn & Play

Mobile softplay (Toys and play equipment hire) / Event Creche hire (For weddings, conferences etc) and Playgroups where children 0-5years come to play with our equipment, Meet new friends and learn by singing and dancing, doing crafts etc!
Target audience-Children 0-5 and Parents!!

Please take a look at the Pics below to help you with the Styles I like.
Also you will see pics of some of the equipment we use to Hire out.
I will need to somehow link the art with the theme of children playing to demonstrate who we are and what we do.

Please feel free to take a look at my site http://www.babblestreet.co.uk
I would like a custom design to add to my website and possibly to our uniform.

Id like Cute (Appropriate for 0-5's), fun, colourful looking characters suitable for 0-5's.

The theme I am using is a Bluebird, Bee and Ladybird the reason for this is because the name BabbleStreet which began as a playgroup comes from the description of the main development of children who regularly use our equipment is talking (Babbling) and the parents who bring their children are also often coming along to chat (or Babble to other parents)
Babbling -> Babble -> BabbleStreet -> Babbling Bird -> Became a Blue Bird.

Since starting the playgroup we have now extended our service and provide a party hire service. This involves delivering Softplay items to venues and houses for Birthday parties.
We also set up wedding venues for Softplay and look after children so adults can relax.

We offer a few packages

1. Themed equipment.
(Bumblebee themed for girls with Space hoppers, Ball pool, Ride ons)
(Red Mopeds, Cars, Softplay bricks and Lego for Boys)

2. Sensory play equipment
(Black, Red and white equipment)
Ladybird Playmats and a Ball pool.

Idea's ...

-Bluebird, Bumblebee and Ladybird characters.

-Cartoon children dressed in Bluebird, Bumblebee and Ladybird outfits.

-A way to incorporate a cartoon drawing of one or all of the characters playing with our equipment!?!
Ie, Bluebird playing with Softplay lego bricks
Ladybird on Spacehopper or Bluebird on Red car or moped

-Characters holding a banner displaying our Tagline (Meet, Learn & Play)

Main requirements.

-Characters need to be cute. Appropriate and appealing for 0-5Years.
-Needs to appeal to both BOYS and GIRLS.
-I am open to idea's BUT like the style of designs I've attached so please consider this when sending designs.
-If Designing cartoon children in themed outfits please can one have orange hair (possiblly freckles on cheeks) <-- I will then tell my daughter she is one of the characters haha!
