Hey guys Im quite new to cox 1 week actualy. Did play it 4 years ago for 2 months I think and a lot has changed since then in this game

Tell me how much money do I need do start the AE runs with this guide? Right now Im doing the missions and story arc with my characters (ss/wp brute rad/rad corr and plant/thorn dom) the normla way and just havng fun with the game. Im not into PL them I want to know the game first and play from lv1 to 50lv the normal way. But gaining tons of inf with a farmer to buy stuff for them would be cool.
In the guide it's said you need 1mil for the insp. to start the runs. If this is true how can a new player get 1mil inf to start? I guess in the AE right? But can I just run missions in the AE with xp off with one of my characters (so I don't outlevel the contacts) and get more inf than doing normal missions?
ps. sorry for the bad grammar Im in a internet caffe right now and don't have time to check how many mistakes I have made

Im better at speaking english than writing in it unfortunately.
