If your intent is to sell, then I would actually start with your brand, not your fragrance. Think about who your company is, what its story line is, and what mission its on, then start sourcing fragrances that support that story line. For example, as you're in OH, and you're doing goats milk soap, so maybe your company story is rural farmy goaty, so scents that are evocative of farm life, fresh breezes, local flowers, fresh grass, etc. You're also near a national forest, if that's a tourist attraction, then something that represents that area, piney, mountainy, etc. I spend a lot of time in the wine area of Geneva, OH each year, so if I was there and creating a line of soaps, I would definitely be capitalizing on fragrances that are evocative of wine, grapes, fall, etc.
Scent sells soap, and your storyline is what makes the fragrances you choose unique and special to you, and people love to buy stories as much as they do the scent.
And you'll have to bend... I am not a patch lover, but many people I know are, so I'm working on patch soaps that complement my storyline. Same with lavender.
I love bakery scents, but they don't work for my storyline, so I don't use them.
The cotton ball idea is great, but it may not give you the real world feedback you need. A smell in a jar is totally different from one you put on your body and smell like for a while, its just a different context for appreciating the scent. Also, its not uncommon for an FO to radically change as it goes through saponification, so, what you smell on a cotton ball and what you have 6 weeks down the road after curing might be two wildly different things.
From finding FOs that work for you and your story, to finding FOs that work for your recipe, to finding FOs that stay true to your initial vision, to finding FOs that sell... its all trial and error.
