It's possible but not to think enough through the process that you need to create purchases orders large enough to need approvals? However if you don't have a basic understanding of hardware you'll need you probably shouldn't be working/in charge of this proejct anyhow. If you fked up this bad you're in for a bad time regardless of where you've decided to host.
Anyone who thinks they planned everything correctly is just deluding themselves. Admitting you've fucked up, don't know how you fucked up yet but will one day need to fix the fuckup is very important in engineering.
