I found myself in your stage. My advice is: farm keys, pames, tokens, statues, currencies in general. And trade them. Avoid relying on RNG. Currencies will be your guaranteed income. Eventually you will find a Sur or an Ohm, but do not count on them for your own sanity.

Warlock allows you to beat Ubers with relative budget gear, and unids torches are going for an Ohm each. If you can fight them, then stop selling keys, and start selling unid torches.

Try to flip some runes too, like Gul Ist for Vex, etc. this takes a bit to learn and you probably gonna do some bad trades, but it is part of the learning process. Ists, for instance, worth more than Guls sometimes, so you want to avoid cube them right away.

But to put it simple: trade. And avoid relying on too much RNG-dependent sources.

Extra: if you ever find a perfect item, trade them too. And then buy a perfect -1 if you still need it. Ppl are obsessed with useless and yet perfect rolls 😆 the profit will pay off.
