In a couple of days there will be a link to allow a limited number of people to become a host. What I would suggest is to compile a list of people with similar interests on steem. For instance you are interested in photography. If you have a group of people who also post photos, you would be similar in appearance to this website:
https://www.outdoorphotographer.com/
While the cosmetics of outdoorphotographer exceeds the layout that your own group would currently have ...

steemhost.com/@n0man (does not have any of the additional text or images enabled)

steemit.com/@n0man

busy.org/@n0man

we will be altering the template (perhaps have a selection of templates) to display your content as well as contributors who you might select. This would allow you to create your own "Outdoor Photography Magazine" perhaps specific to Bangladesh.
