Seeking VA for sourcing, engaging and negotiating with vendors / suppliers for ecommerce company

I'm seeking a competent and qualified VA with good writing and speaking skills to assist with the sourcing of new US-based vendors and / or suppliers in a specific niche category. Once these vendors are sourced and an account is initiated, your task would be to inquire and obtain inventory lists with qty's, pricing, etc. You will also be tasked with utilizing your negotiating skills to try to secure the best possible terms and prices possible with the vendor.
