If it is just an idea at this stage it may feel like it has value, but believe me, it does not.

In order for an idea to have value you actually have to build something. If you can't be bothered to build something, it probably isn't a very exciting idea. So what you are trying to sell is an idea that you, by your own admission, don't think is very exciting. And what you have is essentially something you could put together in an afternoon.

The maximum I have ever paid for an idea is lunch. If I have reason to believe that someone will be able to interest me long enough that I'll make it through lunch, heck, I'll buy them lunch

If you want to transform it into value, you need to do a bit more. If the idea is really so boring that you won't, you could pay someone to work on the idea or you could partner up with someone. Freeing you up to have other ideas or whatever you are doing that is more fun than acting on the idea you are trying to sell.

Now here is a free tip: if you take an idea to a bigger audience, you may find other people that are interested in it. People who might want to do it. People that might have other ideas because of it. And yes, people who will tell you that your idea is rubbish. If your idea is good, someone might want to do it on their own. But this is less likely than you think. Because other people also have ideas. But in any case, if you tell more people about your idea you stand a bigger chance of getting help. Start with people you know who have built stuff.
