Firstly I would ask you, why do you want 1million results?
Also, 9/10 unfortunately people who need to ask this question, are not going to be capable to get it.
5 accounts on your home IP isn't that much better than 1 accounts. It's all from your home IP. How many profiles does a normal account look at daily? 100 maybe? Assuming you can use your 5 accounts, that is 2000 days to get a million. So 5 years
Rather than go for bulk, go for quality. If you are sure you want to aim for a million, then you will need to just start small and build up, face the issues you will face, solve them and keep going at it, learning as you go. Then during the process, you probably realise you don't need those million results and change the plan
