Minimalist WordPress PO Portal

I need a brand-new WordPress site that does one thing perfectly: issue and track purchase order numbers. The landing page must be ultra-lightweight, loading almost instantly, and present a clean “Request for PO#” form with five fields (equipment, supplier, item, cost, requester email)...
