It was me that locked your original post, and it was done partly for your benefit.
Yes, of course you are free to set your own price for trades but as your valuation was so massively different from the average current prices those items have been selling for, there was a high likelihood that you'd just get a load of spam and abuse.
If you're prepared for that then go for it but be aware of the points I made above.
If anyone starts griefing you on the thread, please don't retaliate, report it here and we'll take a look.
I'll notify my fellow FMods about this, so your new thread should be ok as long as any arguments don't get out of hand.
Hope you understand my reasons for the original lock and no hard feelings.
Who's the cat that won't cop out when there's danger all about?
