Make a new photo slideshow

I have a presentation that I will use at work tomorrow. I have taken a about 30-40 pictures and 4-7 videos that I want to use in the presentation. I will send the pictures and videos as soon as you accept. What I want is simple: - I want a photo/(video) slideshow that smothly changes from one picture to another (or a video) there should be a smooth transition between the pictures with not "to much" effects. - I want to change pictures myself by pressing a key on the keyboard. I will pay 20 USD for the job. Please dont make an offer if you cant do the job for this amount. The job has to be finished within 12 hours. Please specify the program you want to use.
