Do recite Narayanakavacham 3 times in the morning and 3 times in the evening before bedtime and continue this for 108 days and you will certainly get a job by the time you learn it by heart. You can download it from http://www.youtube.com/watch?v=oN1UacxhBw0
If by any chance you are Sivaite, you can recite Peaceful Aum Namassivaya Mantra which also you can download from the net.
In your case with a poor strength for the horoscope, only God can help and you have to do the prayers yourself with total dedication till your wishes are fulfilled and cannot delegate it some other medium.
Best of luck.
