Instagram Management page

Hi guys,
I’m new here and I am trilled to find that there is such a big community on this platform.

i need a little help. I am a social media marketer, but I don’t know much about websites. All I know is that i want to build a website for iinstagram management (+other services) that is highly responsive, clean that has the following:

  1. A way to get peoples emails
  2. A way people would be able to enroll on a free trial
  3. Payment facility through a 3rd party payment system

So my question is: Which one of the themes available to buy will incorporate all this for a noob like me?

Any help is welcome! Cheers!

You didn’t write too much about specifications, but if you dont have experience it is better to hire someone who will build your site. Invest in stock images. good hosting any quality designer.
