Much was already said in this thread, but until now, there is no many jobs offering $1 hourly for simple tasks. There is more people looking for jobs than people offering jobs. So it's hard for us to find services.
And captcha jobs are paying only $0.3-$0.4 per 1000 captchas solved, doesn't worth.
Captcha works are really doesn't works, you can't even solve 15 captchas a Minute and 1000 captcha an hour. so basically with captcha typing you can't earn more then 0.4$.. lots of people still doing captcha work because it is sill better then faucets and ptc sites which pay very less for work.
finding a job for 1$ hour is not easy at the web. but if you use your mind you can make more then 1$. like if you are good in marketing you can use a site's affliate program and make referrals for them. and get commission, it can take some time but after few weeks you'll get full reward of your spent time.
Same as blogging. you need to spend some time on blogging but when your blog will be able monetize you'll be in profit.
