3 separate original drawings / illustrations for product box

This is a request for an artist / illustrator who can provide 3 separate bright, funny, cartoon-like illustrations /pictures that we will use to illustrate how a new child alarm product that we are launching actually works. The pictures will be used on the retail box for the product and on flyers/other advertising materials etc. The illustrations we require must be completely original, purely your own work, and 2 at least will need to be of either young children or of a baby in a pose/attitude that we will describe in more detail (to communicate to a prospective buyer how the child alarm works) when we receive initial quotes from people interested in this work. We do not mind how the illustrations are prepared (whether drawn freehand or with computer package) but the end file for each image needs to be something we can easily reproduce in print to any size. The style of illustration required is very much in the humourous 'fun' style, by this I mean we are hoping to get the sort of illustration that makes people smile. We are looking for work in the style of the attached scrapbook we have put together. Therefore, we are looking for somebody who can create a humourous child and humourous baby, who will be wearing one of our child alarms. Parents will need to identify with this child or baby and with the type of situation we want you to put the child or baby in. The third image we need will probably need to be some form of humourous animal, that a child will identify with. Maybe a freindly dragon? This will be in effect be a logo image that will be printed onto the alarm device itself that the child wears. We will explain this image in a little more detail once we start contacting people interested in this project.
