Professional Sales Presentation Deck

I am looking for help to make a product portfolio sales presentation look much more professional. I will supply a deck of c.30 slides with 90% of the content completed (the remainder must be possible to add in subsequently). Pictures and visuals are currently placeholders - some of which might not have copyright approval. I need c.30 pictures to be found and added to the deck, and all the slides tidied up , along with some smart linking from the central slide to each of the different subjects sections.
Some of the language could probably also do with tweaking, but I can do that after I have the first draft.
I expect this to go through 2 edits at least. Ideally, first draft in 48 hours, 2nd draft 48 hours after feedback.
There is a corporate template that I am using, so no need to design that.
The price should include the cost of any stock images / photos.
