Dear,
You can find in my portfolio two games I already programmed before. The first one is Simple Typing Game in which the child will type on the keyboard the letter he sees on the screen. The second one is a Word Guessing Game where the child will guess a word, represented as *, by guessing one character at a time. Some modifications can be made easily upon your request.
I can also design the game you mentioned in your proposal, where some products will be shown to the child and he will decide where to put them.
If no modifications are needed I will give you the first two games within 24 hours, otherwise, each one might take up to two days. The Classifying Game you mentioned will take about 7 days.
I would be happy to work with you.
