1. This is NOT a UK forum. I know but i think most members on here are British or study in the UK

2. Any moronic scammer can pay a small fee to acquire a "Companies House Number." It is in no way whatsoever an indicator of quality or trustworthiness. True but its a good sign since the companies house perform a credit search on the director so you have to have a UK address and need to be solvent.

3. Please don't misrepresent as fact what is only your ill-informed and incorrect speculation. Its neither ill-informed or incorrect speculation. I think you'll find that most if not all scam sites do not have a companies house number. If it was that simple to get as you're suggesting then surely they'd get one wouldn't they.

There are one of two indicators eg a companies house number is a good sign as is business account with a high street bank. Call them and ask them questions and then take things from there if you feel reasonably confident

If you are not a smart student - the only thing you could do is search through google and try and choose a company that seems honest. Otherwise, search on this site or use services that are recommended here.

No one can guarantee your mark. If they said they can get your 65-69% then the fact that you got 48% proves my point

I think there are too many of them already out there for you to make a living from this

How can you expect a top class essay from someone whose first language isn't even English? It just would not make sense to hire an Indian writer. There is a reason why legitimate companies clearly state "native writers only". There is also a reason why the UK does not hire people from abroad to fill their teaching positions.
