There is no saint quite like St. Joseph to pray to for any special intention. St. Teresa of Avila said: "I wish I could persuade everyone to be devoted to this glorious saint for I have great experience of the blessings which he can obtain from God. I have never known anyone to be truly devoted to him and render him particular services who did not notably advance in virtue for he gives very real help to souls who commend themselves to him."
I just wanted to share this devotion of a 30 Day Prayer to St. Joseph. I have never known it to fail!
"Ever blessed and glorious St. Joseph, kind and loving father, and helpful friend of all in sorrow! Thou art the good father and protector of orphans, the defender of the defenseless, the patron of those in need and sorrow. Look kindly on my request. My sins have drawn down on me the just displeasure of my God, and so I am surrounded with unhappiness. To thee, loving guardian of the Family of Nazareth, do I go for help and protection. Listen, then, I beg thee, with fatherly concern, to my earnest prayers, and obtain for me the favors I ask. I ask it by the infinite mercy of the eternal Son of God, which moved Him to take our nature and to be born into this world of sorrow. I ask it by the weariness and suffering thou didst endure when thou didst find no shelter at the inn of Bethlehem for the Holy Virgin, nor a house where the Son of God could be born. Then, being everywhere refused, thou hadst to allow the Queen of Heaven to give birth to the world's Redeemer in a cave. I ask it by the loveliness and power of that sacred Name, Jesus, which thou didst confer on the adorable Infant. I ask it by the painful torture thou didst feel at the prophecy of holy Simeon, which declared the Child Jesus and His holy Mother future victims of our sins and of their great love for us. I ask it through thy sorrow and pain of soul when the angel declared to thee that the life of the Child Jesus was sought by His enemies. From their evil plan, thou hadst to flee with Him and His Blessed Mother to Egypt. I ask it by all the suffering, weariness, and labors of that long and dangerous journey. I ask it by all thy care to protect the Sacred Child and His Immaculate Mother during thy second journey, when thou wert ordered to return to thine own country. I ask it by thy peaceful life in Nazareth where thou didst meet with so many joys and sorrows. I ask it by thy great distress when the adorable Child was lost to thee and His Mother for three days. I ask it by thy joy at finding Him in the temple, and by the comfort thou didst find at Nazareth, while living in the company of the Child Jesus. I ask it by the wonderful submission He showed in His obedience to thee. I ask it by the perfect love and conformity thou didst show in accepting the Divine order to depart from this life, and from the company of Jesus and Mary. I ask it by the joy which filled thy soul, when the Redeemer of the world, triumphant over death and hell, entered into the possession of His kingdom and led thee into it with special honors. I ask it through Mary's glorious Assumption, and through that endless happiness thou hast with her in the presence of God. O good father! I beg thee, by all thy sufferings, sorrows, and joys, to hear me and obtain for me what I ask. (mention your petitions) Obtain for all those who have asked my prayers everything that is useful to them in the plan of God. Finally, my dear patron and father, be with me and all who are dear to me in our last moments, that we may eternally sing the praises of Jesus, Mary, and Joseph. A blameless life, St. Joseph, may we lead, by thy kind patronage from danger freed. Amen."
