Let's write a healthcare bill

So far it doesn’t seem like the republicans have a bill in place for a replacement to Obamacare. I know that they tried to submit votes when Obama was in office because he vetoed something, but they haven’t voted on something since trump went into office. So I was wondering what parts would you have in a healthcare bill? Try and think of serious stuff. For example if you want something for free someone else will have to pay for it. I was wondering if I would try and submit it to my senator to maybe help the process along.
