Although BidBuy may display this as 'Net Unit Cost' and 'Total Cost' in dollars, remember the actual unit of measurement is a percentage.

Carefully review all contract documents and attachments to fully understand the scope of services required for operating the lodge and restaurant. Highlight your experience in managing similar facilities and your plan for ensuring high-quality service to park visitors. A clear and well-supported proposal for your proposed percentage will be key.
