I was wondering if there are any platforms that I could use.

If not, do I have to code one for myself? My coding knowledge isn't too great - It would take me about three days using javascript and HTML.

I would really appreciate it if somebody could give me some help or possibly even code one for me  .
Or could anyone give me the code for a landing page that they have already created (I'll edit it of course so it doesn't look exactly the same)

Thanks
