Help me finish a PPT slide presentation

I have 2 sets of about 70 mixed slides that need to be formatted into a new uniform style, which I provide. The company logo needs to be put on the lower left of each slide. The two sets should remain separate. There isn't enough file room to include the logo, but it is ready.

Have a look at the attached and make me an offer. Also, let me know if you have any creative ideas to make it look better or for interesting slide changes. Thank you. Alan
