animated banner design and gif creation

I will not respond unless you ad the following into the subject "gif master" I need five different animated .gif ads created for online advertising that I am doing. We will create the five different ads. I have the copy and can share with you photoshop files of what we are doing. There will be a main design that will have the body of the design change out three times with different info on our company. The file size max for each file has to be 40kb or less and will be 15 seconds max. **Please check the attached for examples** Once they are created I will need the designer to than make them into the following sizes for each advertisements 300 x 250, 336 x 280, 728 x 90, 160 x 600, 320x50
