High-Quality B2B Prospect List Creation (Phone Numbers Mandatory)

I run a B2B cold calling operation and need a reliable freelancer to build a high-quality prospect list for our sales team, who dial roughly 100 prospects per day. This is a one-time project — I need a single list delivered, not an ongoing series. Target criteria for leads: Company size: 1–50 employees, prioritizing companies with 5–50 employees once enough results are available in that range Location: United States Industries: Retail, Consumer Goods, Apparel & Fashion, Cosmetics/Beauty, Food & Beverage, Health & Wellness, Sporting Goods, Jewelry, Home Goods, and E-commerce Company keywords to prioritize: Shopify, ecommerce, e-commerce, online store, DTC, direct-to-consumer, online retail Decision-makers: One contact per company — Founders, Co-Founders, Owners, CEOs, or Presidents What I need per lead: Company name, contact name, title, direct phone number, email, industry, employee count/company size, location Verified, accurate, up-to-date data — no outdated or disconnected numbers No duplicates within the list Deliverables: One completed list delivered in CSV/Google Sheets format Clear documentation of data sources and verification method used
