Hmm I think I have an apartment because each time I start the game I respawn in a garage under the apartment, I guess I must have one then?
What are the import/export missions Ayahuasca?
And whats the bunker for?
I currently have around 1.5m cash... what can I do with this to get the ball rolling?
Money makes money etc.
first advice i'd give is try and wait to buy most things when they're on offer, every Thursday around 10am the game has a weekly update where some propertys and business's can be discounted by upto 50%
(with that said though, you do need to get some type of business up and running pretty soon)
the past week the major discount was on Yachts which are of no use to you atm as even with the discount they start at around $4 million
so wait until tomorrow (Thursday) and see whats on offer
you can find details of what's discounted in the weekly updates here..

or you can search 'GTA weekly update' on youtube, which is probably best as youtubers fall over themselfs trying to be the first one to post the weekly discounts,
also some activitys will pay double or tripple cash and RP, this also changes every Thursday with the weekly update, so check that so you know where to spend your time grinding for money.
the 3 main business's you want to try and get first are a Bunker, a Vehicle Warehouse (vehicle cargo), and an crate Warehouse (special cargo)
(You will need to buy a CEO office before you can buy a vehicle or crate warehouse though)
get them in locations around the middle/top of the city, stay away from locations at the top of the map,
i'd start with a bunker, either the farmhouse or chumash location and buy the staff and equipment upgrades as soon as you can, no need for security upgrade to start with,
and set it to use your supplies to gain 'stock', setting it to 'reserch' is a waste of time to begin with,
the bunker is a passive business, you set your staff to make guns with the supplies you either buy or steal, then you sell them once they're done.
Also don't waste money by buying cars or clothes! and make sure you spin the lucky wheel in the Casino every day as that can earn you free cars/clothes/money and RP
