Financial model for a pre-sold Japan→US sourcing offer (Spread Scout Japan)

Small paid test. I have a product-market discovery report for a pre-sold Japan→US sourcing desk called Spread Scout Japan, and I need the money math built on it plus an honest assessment. THE OFFER: A US customer sends a specific Japanese item they want (starting with used camera/lens gear and narrow collector goods). I return three Japan-source options with a landed-cost quote (item + Japan domestic shipping + international shipping + estimated duties/fees + my margin), a condition/authenticity screen, and a purchase recommendation. The customer pays a deposit BEFORE anything is bought — no inventory, buyer funds the purchase, I keep the sourcing fee/markup. RANKED OPPORTUNITIES: 1) Pre-sold sourcing desk for compact high-value goods — cash in 7-14 days, near-zero capital. 2) Used Japanese camera/lens sourcing — 10-21 days. 3) Official fandom/collector drop concierge — 7-21 days. 4) Micro-wholesale sourcing for US specialty retailers — 21-45 days. 5) Reverse sourcing: US products for Japanese buyers — 14-30 days. 30-DAY PLAN: Days 1-3 pick the wedge (camera gear) and set the quote formula. Days 4-7 prove the spread — 20 real Japanese listings vs 20 US sold prices. Days 8-14 pre-sell — post 10 wanted-item examples, goal 10 requests, 3 quotes, 1 paid deposit. Days 15-21 fulfill one transaction, buyer-funded. Days 22-30 decide. Pass/fail: one paid order, 20%+ gross contribution after direct costs, repeatable in under 2 hours of my time. DELIVERABLE: (1) Your honest take — does this hold up? What would you change? (2) The money math — startup costs, margins per order, break-even, and monthly run cost with a VA handling listings/translation/updates. (3) Your price for this first piece and turnaround time. Hourly project, $2–8/hr. No work and no time tracking until I send the first brief — please bid with your hourly rate and turnaround time.
