Grow DealDetective’s First 100 Users

I need a marketing freelancer to get the first users for DealDetective (ddec.co.uk), a UK web app and browser extension that shows online sellers the real profit on wholesale products before they buy. Users paste a supplier link (Alibaba, AliExpress, Faire, Ankorstore, CJdropshipping) and get landed cost, marketplace fees, VAT and profit for selling on Amazon UK, eBay, Etsy or their own store. There's a free plan and paid plans.

Target audience:
- UK side hustlers and small online sellers who buy stock to resell
- Often not VAT registered and not confident with numbers
- Wary of hype and "course sellers"
- Found in seller Facebook groups, Reddit, YouTube, TikTok and seller forums

What I need (8 to 12 weeks, open to your ideas):
- A plan to get our first free sign-ups and paying users
- Helpful, non-spammy posts in seller communities
- Short videos showing the tool working out a real product's profit
- Outreach to UK e-commerce YouTubers, TikTokers and newsletters
- Promoting our existing guides at ddec.co.uk/guides
- Small paid ad tests only if you think they'll work, with budget agreed first
- A short weekly report: what you did, sign-ups, what to change

About you:
- Proven results getting users for a SaaS, app or e-commerce tool (please share numbers)
- Ideally you know the Amazon FBA or UK e-commerce seller world
- Excellent written English, plain and honest tone
- No fake reviews, bought followers or misleading claims

In your proposal, please include:
1. Two or three examples of growth you've driven, with numbers
2. How you'd get DealDetective its first 100 users, in five bullet points or fewer
3. Your price and availability
