3m cash to 16m junk. How?

I'm looking to sell my battle robes and I've gotten offers of up to 16m. I only have 3 mil to work with . How do I obtain this much junk?

 

get chicken eggs+cobra pouch+summon the cobra+use cobra scrolls with eggs in invy 2m+ junk made every hr or more

 

Any other methods? I want something quick.

 

2m junk an hour is pretty quick considering you probably need to buy a method that can make more than that per hour.

 

I'd gladly buy it but I haven't seen a guide for it in the appropriate section.
