To me, if building a landing page seems like too much work, you might not have enough enthusiasm for the idea to do the heavy lifting that comes later. And often, building a landing page is a way of playing house. It seems like progress but it isn't because it doesn't move the product forward and does not gain actual users. It provides an excuse to avoid those unpleasant tasks. If you really want to go down the landing page route, be serious and ask for money. People's willingness to pay you while knowing the product does not exist is reasonable validation...though of course you have to do "successful kickstarter" level work. Anyway, in the time it takes to read this, a person could be halfway done with HTML and Javascript and a Google Sheet for a landing page. Good luck.
