Good day !

I've been reading a lot of blogs about about this microstocks already and most of the articles i read are..
"dont give up" "its not that hard" "get 500 bucks a week" and more blah blah blah.
This is the first forum i've seen and i've been lurking and reading some threads already,
this is the only place where i people take mstocking seriously than the blogs i've read.
i've been thinking about introducing myself.,,,so here it is.

Im a portrait photographer for about 4 years already, an Automotive Mechanic by profession.
 I've been shooting cosplay,back up at weddings, and a few from my travels.
I only HAD a 60d and a few lenses and flash, i rent few more gears when i shoot weddings.

Few weeks ago my 60d died with about 400k actuations. and with a small pay i receive from repairing cars I couldnt afford anymore gadgets. So i decided to sell some of my flash and 70-200 f4 leaving a pair of Yongnuo 560's and a 50mm 1.8 just incase i could afford
a 2nd hand 5d mark1(atleast i could experience a full frame).
While surfing at youtube i saw a vid about making money from stock photos, I was thinking well, i have about 2TBytes of photos well maybe this could do.Hoping this could make me buy a new camera before i run out of photos.

btw, i've already sent some of my photos to about 9 agencies already hoping I could pass atleast 3 agencies.

Newbie Question:
1. how long before you guys made like a $100? so far i have 50 photos re-processed for stock.

2. and do you type all those keywords per image? took me about 2hours to keyword 50images.

3. If i pursue MStocking with this quality of shooting (https://www.flickr.com/photos/cysarsoriano/sets/)
dedicating about 20hours a week. would that be good enough or this Microstock thing is not for the faint of heart?

Thanks For Reading and I'll wait for your comments.
sorry for my bad english.
