Bid Writing / Bid Administration

I'm currently after a Bid Coordinator/Writer who can handle some basic responses, fill in SQs and do Bid Plans to support a short-notice gap in our business. Having previous bid experience is a pre-requisite, including using portals, etc. Looking for a minimum of 10 hours per week. Minimum of 2-3 years of experience in public sector bidding is essential with basic editing/writing skills ideally.
