Hey Peter,
Regarding FB crashing, I never said FB crashed, I meant one page can suddenly become unavailable. Trust me I have seen it a few times. And yes SEO-ing FB for one's particular market is not as flexible as having one's own website.
Having a simple website built need not be expensive. There are a lot of service providers in Upwork, in Fiverr, who can do it for a rate way below what you declared. It is a matter of sourcing it.
