Strategy for entering the market with large lump sum

So I will have a significant lump sum of cash to invest in the next 30 days and I’m looking at strategies to deploy it. I understand the percentages of lump sum into the market vs DCA but I am very new to the idea of options/ puts and I’m not sure if I’m missing something because it almost sounds too good to be true. I’m thinking of buying (selling?) 2-3 put contracts with a strike price just below that day’s price on VOO and QQQM for 4 months. The premium for a 4 month contract with a strike just below the current price is significant. I would also sell puts at 15-20% below the current price on VOO and QQQM in case there’s a crash in the next 4 months. The premium for this would be in the 10’s of thousands of dollars just to invest money that I was going to invest anyway and at cheaper prices. Am I missing something? Is there an inherent risk I’m not accounting for? Yes, I realize that if the market shoots up and the price never drops from that day on, then I would be missing out on some gains, but I’d still have the huge premium + 3.5% on the cash in a money market. It’s also hard to believe that the day I sell the puts will be the very bottom of the market, especially with the pre midterm volatility we’re going into. Even if I ended up having to pay out on all 4 puts, that would still leave me like 20-25% in cash and 75-80% of my portfolio owning VOO and QQQM at good/great prices. Again, I’m new to options and mostly have been talking to ChatGPT for ideas, so please let me know if this is a good strategy or if there’s something I’m missing.
