Sourcing digital codes that don’t require invoices

I run a new site selling digital codes and don’t have business invoices or reseller docs yet. I need a sourcing specialist to find 3 verified suppliers or authorised resellers who can work with a new/individual seller (or propose viable alternatives like dropship/fulfilment partners), and — if possible — arrange a small pilot order.

Deliverables (compact)
- Shortlist of 3 suppliers with contact, MOQ, price estimate, payment methods, and lead time
- Onboarding requirements for each (what paperwork they ask for) and simple workarounds if invoices are required
- Quote/arrangement for a small pilot order (if supplier willing) or clear next steps to place it
- One-page recommendation and 7–10 day action plan
