Bulk English Learning Question Bank

I am building new content for our app so i need both (types&pattern) SpeakX-style drills and Duolingo-inspired lessons and need a complete question bank to plug straight into the platform. The goal is 2,000 – 3,000 well-written English questions that span beginner, intermediate and advanced levels... (Budget: ₹1500 - ₹12500 INR, Jobs: Audio Services, Content Development, Content Writing, Data Entry, Data Processing, Educational Research, English Translation, Excel)
