Not a bad idea. Venture into agriculture online. I can build a platform like thriveagric.com with Just N120k, U register a company name with CAC with N80k. You will still have N800 balance.
From your 800k balance, u will spend 200k on social media sponsored advert which I can also handle. Secure a virtual office in Lagos and Abuja for a year for another 200k(100k) each. Now u you are in business with N400k account balance.

Start sourcing for land to hire for farming.
