Do you really expect one customer to pay you 330,000 USD for your skill implants and 55,000 USD for items? You have been trying to sell it for about 1,5 year. Why don't you just sell it to many players? Who in the world can afford to pay circa 400k USD to become super-skilled player?
I have just finished my Berycled Iron IV killing only youngs. I am at 94,765% in TT return. Also looted tones of Animal Oil sold on average for 102,5%, some extractors sold for 135% and boards for about 500%.
Fouls Iron III - 91,12% TT, (only youngs -some bones and tons of tier II upgrades)
Kerberos Iron III 117,12% TT (95% youngs/5%matures - only ammo and oils but got one HoF)
Shinkiba Iron IV - 97,014% TT (90% youngs/10% matures - looted some unlimited noob armor parts)
currently aiming on Combimo. I deposited 100usd at the begining but recently bought also 300 ped of boxes, idk why i did it tbh. Also got some peds form selling mentor prize.
I did it with starter pack adjusted armor with limited plates acquired from calypso mission, Z12 barbarella + Sinkadus amp with TT pistol + Omegaton 8 pec amp and gauntlet medkit. I'm a noob so I tiered up z12 and put aim enhancer for crits but resigned after two of them broke. I also bought HP ring for 20 ped.
From what I see your TT returns are similar although you have some access to event tokens and high merkup stuff which bring you to positive return. But events do not last forever and one cannot be always lucky to loot only high mu stuff.
What is the point then in spending 400k USD just to be able to acquire similar or slightly better result than a guy who registered in november, has no more than 30,000 skillpoints and uses most basic items?
Still, good luck with selling this. With the cost of esi you would receive about 150,000 usd which would allow you to buy
Brand new Audi R8 Spider,
140x Gucci G-Timeless watches
3 kilogram gold bar
Potential buyer would have to pay 400k usd, instead of he could get:
Two brand new Lamborghini LP 580-2 Coupe RWD or
Conam 58 HT Sportboat or,
Two 750 square feet apartments on 526 West 158St on Manhattan, New York or
2630 Apple Inc. shares on NASDAQ or
18 acres tropical island Motu Tohepuku in French Polynesia
This is beyond everything to me how expensive this game can get. It's incredible that one single avatar can achieve so much value.
But imho, selling this all to one customer at once is impossible - better consider selling it partially.
Good luck.
