Non-Profit Outdoor Gear Marketplace Development

i want to create a marketplace for canada like vinted/buycycle but it should be non profit. i want a community which sells skis, snowboards, cycling and outdoor related stuff between them. possibly it would be nice to have a blog section dedicated and shipment options offered by other providers...
