If you want my advice set something like following in your guide:
A trojan will take LOTS of potion (which also means gold) to get to lvl 100, without a set of minimal elite+3 set of defence equipment(armor, coronet, necklace). Trojan is the 2nd slowest class to level so you might wanna begin by making some money with other character for minimal survival gear.
A lots easier alternative is getting a warrior/ninja/archer to lvl 120 and enlighten your trojan(Or asking people for enlightens), while spending the rest of time in training ground getting your weapons proficiencies leveled up.
WHEN you reach 100 start leveling up actively
Suggestions for money-making:
Archer: ~lvl 100 Scatter at apes lowest level apes. Pick up any gold except for the silver piles (below 100 silver). Collect and check every item, drop whatever you think is not worth selling to people.
Warrior: ~lvl 100+ spam superman with wand at Birdmen / Hawkkings at BI. Only collect large piles of gold and valuables (gems/mets/DBs etc.)
Any lvl 70 character on mining: It's rather passive so you might wanna use this in addition to active money-making (marketing, monster farming w/e).
Blue rat quest (i believe it's mentioned in the guide).
