A business opportunity to earn extremely high income — up to 1 million yen per month possible!!
Literal
Extremely high income [object-を] obtain chance [subject-が] exist business, monthly 1-million-yen possible!!
Advertising copy, likely spam or a dubious business pitch. 非常に ('extremely') is formal but used here for grandiose effect. 月額１００万円可能 is a telegraphic noun phrase — no verb, just 'monthly 1 million yen possible.' The double exclamation marks (！！) and the breathless promise are hallmarks of get-rich-quick schemes. The sentence structure is intentionally fragmented for impact, mimicking headline or banner-ad style.
