Hello,
I have taken a good look at the information on the pictures. (Had to go through a little hack to view them tho). The task is quite simple and I have experience with such already. I am ready to get the work well done for you. I will take some time and pay detailed attention to the analysis (I mean analyzing the requirements you gave) and bring out a good class diagram which respects OOP.
To cut the long story short, I intend to deliver between two to three days if I am awarded and begin today... I also look forward to hearing from you.
Regards,
Didier.
