Can't personally vouch for a specific Nigeria hoster from our side — we don't run racks there — but the diligence checklist is the same wherever the cheap power is:
1) Get the real all-in kWh (not the marketing rate). Ask what's included: cooling, PDU, internet, spare PSU, onsite hands.
2) Uptime history + who pages you at 3am when a breaker trips.
3) Contract: who owns the miner if the site disappears, insurance, exit/shipping terms.
4) Remote visibility — if they won't give you hashrate/reject stats you can check yourself, walk away.
5) Start with 1–2 machines before shipping a container.
For remote fleets we care more about "did it go offline" than the brochure. Wrote how we monitor multi-site boxes here (disclosure: Hashrate Farm / Farm Manager):

Hosting providers typically don't take 1-2 ASICs, they don't need clients like that. In my country, a reputable hosting provider takes at least one container with 100 ASICs to ensure the miner gets a competitive electricity price. I've seen offers for 10 ASICs, and the hosting provider is reputable, but electricity costs are high, and those 10 ASICs will cover the electricity and rental costs.
