Give me a strategy for getting to 500% multiplier and/or donut farming?

To the original question I don't have any "collections" like signs or news vans etc. my multiplier is 466 and change and I did it by just getting the premiums that I 1. Like, 2. Can incorporate into my design and 3. I did get all the hideaways because they can be made to look cool and that's 100% to the multiplier :)
Also, I have patience and know how to hide things when I have to
