You know, the main complaint about 1.01 was it was far too easy to make huge amounts of money, so if you can't do that you're doing something far wrong. I don't mean that as an insult, I just mean I think you must be missing some vital step.
In general, in 1.01, you can convert your entire population into craftsmen and clerks and stick them into high value goods factories to make insane amounts of money. Perhaps keep some pops in Iron, coal and sulphur RGOs if the WM is short without your input.
Pick a high value good, like lux clothes, build a ton of factories and either build fabric and reg clothes factories to supply them or just import them. Build railroads all over to icrease your factories effectivness. Don't bother with low value goods, you can mostly import them easily in 1.01.
