Hey guys, I want to set up a business/charity/social enteprise (no idea which to class it as) in the UK and need some advice on how to do it

I want to provide a specific (un-named) demographic with information in the form of a website, information which they need to deal with their situation.

I can build the website myself and could easily set it up to earn revenue from adsene etc however I want it to be able to accept donations for upkeep in a legal manner and I don't know which classification of organisation to go with.

On one hand I want the freedom of running it as a busines and being able to remain in charge rather than splitting it up to multiple trustees but I want to be able to accept money for the upkeep, marketing and my time.
