TBH if I were you I would look into leveling guides.
Just something I found real quick :
1-2 Chapter 1 - Rose Club
3-5 Chapter 2 - Taskmaster instance: Kill mobs and reset
6-10 Chapter 2 - Hood instance: lots of mobs to kill and reset instance, boss is a waste of time
6-19 Lower side east - Str characters can throw cars at mobs for faster leveling
11-13 Chapter 3 - Elektra Hand Tower
14-17 Chapter 4 - Upper Street / Fisk tower / Morlock Underground
17-19 Chapter 6 - Magneto instance (Command Bunker): kill mobs
20-23 Chapter 7 - Evo Chamber/SHIELD Science station: kill and reset (using mob tracker is nice to see the insects)
22-23 Run Green Terminal - Subway/Kingpin
23-24 Madripoor - run if you can get a group for 3+
25+ Limbos are good exp now
Set away about 4 Hours of time.
Set up a timer and start it right when you enter the game with a brand new character. Rush to 25. This will give you a good idea on how long it will take you.
Once you have a set time of how long an 1-25 will take you can get somewhat of a price. If you think this will take you countless hours and are expecting to get tons of XP by being the first person, I don't know how well it will go.
However if you come up with an affordable price and a time frame I am sure you could pick up many jobs as people love playing different Heroes.
Good luck with your service
