Hello!!

 Its always difficult but most at times one could be lucky to secure a job and be hired by a client. But don't despair and but be patient, go for jobs you are very perfect at, one day you will be hired. When i first got hired it looked like a miracle, but i wasoverwhelmed especially when i cashed my money. One day you will equally cashout, just keep posting and writing proposals. GOODLUCK!!
