Expert Sales and Project Management for Sports Card Consignment & Portfolio Operations Specialist

PLEASE THOROUGHLY REVIEW ATTACHED SPORTSCARD SALES AND CONSIGNMENT PLAN DOCUMENT Seeking an exceptional, detail-obsessed freelancer to help operate and optimize a 100,000-card sports card portfolio across multiple selling platforms, including eBay, COMC, PC Sportscards (PCS), and PSA Vault. This role is ideal for someone who lives at the intersection of sports cards, marketplaces, data, and systems. You will also be doing extensive research to open up new markets, as we have a lot of unique and valuable cards that need to be maximized, and we have potential nontraditional buying opportunities to create for lessor known future stars. Role Overview You will help implement and manage a multi-platform consignment strategy designed to maximize net proceeds from a ~100K-card collection with an estimated list value of ~$5M. The portfolio is segmented into high-value, mid-range, and low-value tiers, each routed to different selling channels for optimal fees, velocity, and net profit. You will also develop our unique buying opportunities including athlete relationships and development. Key Responsibilities Execute platform routing rules for each card tier (sub-$50, $50–$250, $250–$1,000, $1,000+) to ensure every card is listed on the highest-net-proceeds channel (COMC, PCS/eBay, direct eBay, or PSA Vault). Maintain and update a centralized “Inventory Map” workbook as the single source of truth for which cards are on which platform, at what price, and under which consignor. Coordinate with a network of eBay consignors for approximately 30,000 low-value cards, including outreach, onboarding, commission negotiation (15–20%), and matching card types to seller strengths. Monitor platform fee structures (eBay, COMC, PCS, PSA Vault) and propose routing adjustments when fees or promotions change. Track sell-through rates by tier (high, mid, low) and support monthly revenue and P&L reporting in line with the existing tiered model assumptions. Help identify misrouted inventory (e.g., cash-out on COMC instead of credit, expensive cards not on PCS) and recommend corrections that can unlock 2–8% additional net proceeds. Highly responsibly develop and maintain athlete relationships with developing future stars, to facilitate sportscard purchases. Ideal Candidate Profile Deep familiarity with sports card marketplaces, especially eBay, COMC, and consignment sellers; prior experience with PCS or PSA Vault is a strong plus. Strong spreadsheet and data skills (Excel or Google Sheets) with the ability to manage complex, multi-tab workbooks and run simple fee/revenue comparisons by channel. Proven experience working with consignment, inventory, or multi-platform e-commerce operations where accuracy and consistency are critical. Detail-oriented and process-driven, comfortable with repetitive but high-leverage tasks such as data entry, reconciliations, and price checks against comps. Excellent written communication skills for professional outreach to eBay consignors and clear documentation of processes and changes.
