Allow me to explain our products and services.
Literal
Our-company's products [and-と] business-contents [about-について] explain cause-receive-humbly.
ご説明させていただきます is peak business keigo: ご + 説明 (explain) + させていただく (humbly receive permission to do). This triple-layer humble construction is standard in business presentations despite sounding overwrought to casual speakers. 製品と業務内容 are 'products and business operations.'
