Hi, my name is Matt and can create a PowerPoint presentation for you (22 years a webmaster and PowerPoint pro, 3+ years doing web animations/visualizations, 5+ years engaged in multimedia e-learning for adults).
Do you have all the content for slides and just need to visually enhance them so they are attractive? What about text animations e.g. by 1st level paragraph? Is this only to be imported in e-learning software (like Articulate Storyline) and you want to have it "static" e.g. non-interactive like branching based on the chosen answer?
Then I agree with the terms. Of course images will be stock but royalty free and more or less free (edited in the PhotoShop/GIMP). Even 20 images only for 10 GBP would mean that my work would be almost free. If you have stock images in your organization's library then please provide them and suggest how do you like them used.
The deliverable will be PowerPoint 2010 presentation to be best-compatible with any version of PowerPoint (and importing to e-learning software). All image references (URLs) will be stated in a special list so that you can confirm their royalty free usage. Please advise where to put copyright statements for images that require that in case they have to be on the same slide (usually it's enough to state them at the end, maybe not even visible to the learner, just to be safe for legal purposes etc).
Looking forward to your reply,
Matt
