I’m planning to go full‑time solo with about $30k–40k in savings. I have almost no product research experience. My idea is to use a curated catalog / selective wholesale approach – find 3–5 sub‑categories, pick several products, and order 200–500 units each for testing.

I’d really appreciate advice on:

  1. Software & strategy – Which tools have a logical, data‑driven product research workflow? (Not just random filters.)

  2. Category & marketplace – What types of categories work best for small sellers doing this? Non‑commodity vs. commodity? US vs. smaller marketplaces?

  3. Price range – Low ($10–15), medium ($15–50), or high ($50+)? Which fits this model best?

Thanks in advance.
