Help for the poor

I have a small little laser/cnc. I’m wanting to make a bigger format, larger diode laser cutter/engraver maybe 10 watts or more. I want to find all the parts to build a bigger set up, around 18"X20". I dont know where to go to find all the parts to build a better system…I’m poor and cant afford a 40-60 watt CO2 laser…so I have to be creative. I had access to an Epilog 75 watt laser, it’s what I learned on…but that was $26000. I’m trying to build up to what I want…it’s all I can do. If you have any suggestions, ideas or whatever…I am open to it. I wish I could get the laser I want because I’m good with one…but this virus has destroyed my chances.
