40k with $5000 in 1 month, and you need a realistic idea.
a. You will first of all need more than just basic knowledge of ppc
b. You will need a kickass niche, offer, and copy
c. You will have to have some idea about how to split test offers, copy etc.
d. You will have to get on weeklies with the network if you are trying to stretch that $5k over the month to make $40k. ie. Spend 5k first week and make $8k (hard but not impossible), get paid next week, rinse repeat.
This,
and asking yourself the following questions,
Will I ever be happy if I continue through life with unrealistic expectations?
Am I even giving this 5k a chance by wanting it to do impossible things?
After you asked yourself those - then pace yourself and set goals. If you're asking how to make 40k out of 5k in the newbie forums in 1 month, you will not succeed. Accept this now and take things slow & learn.
Don't be a dumb ass like so many people that burn through their cash by falling in love with easy ideas. Yes, some easy ideas will make you money but you won't find them in a hurry.
