Random crowdsource/brainstorm request -- Does anyone have anyone smart alternatives to event carpeting? (Looking for something more cost effective and more environmentally friendly)

Hey all! I'm looking for large/small format print vendor in Seattle - we're producing a large conference at the convention center & additional events at T-Mobile Park and Climate Pledge arena in the span of a week, so it would be a large ask! Would also love any furniture rental companies as well. Thank you!! 🙂
