so , you have to find the code to do that work. 
here is the npc u want to :  http://www.mediafire.com/?nse5uj8n1tk61b4
go to script ~> _init_.py open and edit these as you want  ~>
REQUESTED_ITEM=9560
REQUESTED_AMOUNT=10

for example: this is the retail :

if you want 25 gb
change :
REQUESTED_ITEM=6522
REQUESTED_AMOUNT=25

first of all do it correctly: 

u have normal scrolls and blessed max to : 30 
so ~>
# Max enchant Settings by scrolls.
EnchantWeaponMax=30
EnchantArmorMax=30
EnchantJewelryMax=30

second of:
add these to crystal(just in case)
 
 
third of:
go to config/protected/other.properties
 
find this~> 
# On / off protection from re-enchant
# The GMs do not apply
# If a player log with an item Over enchanted he will be banned.
# IMPORTANT: Put True for server security.
ProtectorEnchant = False
 
and if this is "ProtectorEnchant = True"
change it to "ProtectorEnchant = False"
 

no problem.please next time be more kind when you ask for help. if you cannot insert those cords go to eclipse ~> datapack~>sql~> spawnlist~> and search for "catacombs" ~> is there is any you just can copy/paste the spoiler i send you .~> save it (you dont have to build eclipse) ~> go to your workspace datapack/sql/spawnlist.sql~> copy that into your deskop .
go to your navicat ~> make an backup~> delete spawnlist ~>
Execute the spawnlist.sql from your deskop into your navicat .Open server and go to any 7s to check

Server update prices cause they sold more adena than you have set them on .
Example: if you set a bid for "crystal x-grade" to "200adena" and this item can sell for "5000"
server updates it and  fix it!
although if you still want it.
(1 option is :all items will sold for 0 adena)
 
go to navicat and run these :
 
UPDATE `armor` SET price = 0 where price> 1;
UPDATE `etcitem` SET price = 0 where price> 1;
UPDATE `weapon` SET price = 0 where price> 1;
