Hello Laura, and thank you for your question(s)!
I am happy that you found our site – please feel free to use it as often as you need. We are able to provide researched-based answers to gardening questions, but unfortunately that does not extend to garden design, and we are not able to visit your property. For help with your garden design, you may want to google “garden designers in 45459 area.” I did, and a number of names and nurseries came up in the search. As far as where to buy plants, we are not able to recommend specific businesses, but again a google search will list the nurseries in your area.
I would ask you to consider using native plants when you are planting. Here is a great article and video as to why:
https://www.audubon.org/content/why-native-plants-matter
Here is a website listing nurseries selling native plants. There is a lot of information on this site too about native plants and why to use them.

A south-facing slopes allows you many plant options, and it seems to me that you may need a mix of sun and shade plants depending on where you are planting on that slope. Here is an article from Penn State Extension defining what “sun” and “shade” mean, including directions on how to determine what you have:
https://extension.psu.edu/planting-in-sun-or-shade
Here is an article from the University of Maryland Extension titled “Native Plants for Sunny Slopes”
https://extension.umd.edu/resource/native-plants-sunny-slopes
and a second titled “Native Plants for Shady Slopes”
https://extension.umd.edu/resource/native-plants-shady-slopes
I would definitely NOT use black landscape fabric. Here is an excellent article on all the reasons why NOT to use it (can you tell I dislike landscape fabric?) from the University of New Hampshire Cooperative Extension:

In regard on how to prevent soil erosion, I would consult with a landscape designer who is able to visit your site, but here is an article from the University of California titled “Preventing Erosion” that will give you a basic understanding of what may need to be done. (The definition of “moderate, steep and steepest” are industry standards, but please do not use the plants suggested in this article as they are recommended for the California growing area, and would not be happy in Ohio.)
If you are considering grasses, please consider our native bunchgrasses (big bluestem, little blue-stem, switchgrass and Indian grass) instead of the non-native and commonly used Miscanthus. Here is a great article from the Illinois Extension on native grasses:

Adding organic material to a planting is always a good thing but I’m not sure what exactly you mean by a plant starter?
To obtain more information on what an individual plant needs to be happy, I would highly recommend using the Missouri Botanical Garden Plant Finder website:

I believe I have answered all your questions (and given you a lot of reading homework!). If you need any more help from us, we are here.
Have a lovely day!
