Ad Group & RSA Creation for Physical Goods / Ecommerce Products

I'm looking for a freelancer who can generate 20-50 keywords (with USA search volume and match types) per ecommerce product, specifically targeting the USA market. Each keyword should be organized into themed ad groups that include 2 Responsive Search Ads (RSAs) with 8+ headlines and 3+ descriptions. The RSAs should be unique to each ad group but can share headlines/descriptions with minor tweaks for relevance. The two RSAs within the same ad group should be an A/B test to see which performs best. Must deliver in Google Sheets or Excel. Example sheet will be provided. Ongoing work for successful candidates.

Requirements:
- usually start from scratch, as I do not have existing keywords or ad groups.
- Deliverables need to be in Google Sheets or Excel
- 2-day turnarounds
- Ongoing work of 8+ products per month if successful.

Ideal Skills:
- SEO/SEM expertise with a focus on ecommerce
- Familiarity with Google Ads and Google Sheets.
- Ability to create engaging RSAs.
- Keyword research tool experience (Google Keyword Planner, SEM Rush, Ahrefs or another tool)
- Quick turnaround without sacrificing quality.
