Usecase description as a Comic - open to bidding

Hi, I would like to express my idea in a Powerpoint slide as a Comic. The idea is about a Mobile App that is used to find free seats in a train. The comic should have about 6x scenes and should fit to one page in a Powerpoint slide. In the scenes the User (the "Hero") is using that Mobile App. Further details will be provided. Pls let me know about the Budget. Thank you. Cheers, Jiri
