Screenprinting Supplies Pricing HELP!!!!

I have closed my screenprinting/embroidery/trophy business and I need to sell all my supplies. I have tons of ink, screens, a 6-panel manual press, flash, heat press, hat press, huge inventory of garments, SWF embroidery machine, thread, hoops, Gravograph engraver, trophy components, and so much more. I don't know how to price all of these items. If anyone has some tips for me I would very much appreciate it.
I hate to part everything out but I have had no luck selling the entire business outright.
