Hi, Scott!
From what I gather, what you need to do is just convert the presentations into larger chunks of text, which I believe can easily be done within the proposed budget.
In my professional opinion, however, I believe it would be better to add some pieces of text at least - since by only converting them, the posts do not "flow". I would propose adding an introduction to each post that explains (briefly) what the post will be dealing with, so that your readers can glance at the couple of sentences and see if what they're looking for would be found in the text.
I understand your need to keep the material in bullet-points, since that would allow professionals looking for concrete answers to be able to jot down what they need/are looking for and move on, and would certainly keep the format as proposed if I were to be hired.
My bid includes the following work:
1. Writing of introductions to each post (if you decide to do so)
2. Converting the presentations into readable text, with formatting (bold, italic, spacing, etc.)
3. Publishing the posts/scheduling them for publishing on your WordPress platform
I would love to hear more about your project (and give some additional ideas of my own), so please do not hesitate to get in touch with me.
Regards,
Marija
