AssalamuAlaykum

Can somebody please have mercy on this dumb soul and explain the following to me before I implode :heated:

1) What in the world are the 7 P's in Marketing?

2) What's the difference (In the most simplest of ways please) between a 'profit' and 'not for profit' business?

3) Memorandum of association?

4) Is there anything in Islam that prohibits registering your business as 'Not for Profit'? Sounds a bit wrong, but maybe thats because in the context I'm talking....it is a bit wrong :-\

WassalamuAlaykum
