Help reunite my son with his father

Two years ago on March 16th 2014, my son's father Mungai returned to his homeland Nairobi, Kenya. Our son Lucian was 4 at the time.
Mungai had many successes along with many struggles while in the United States. His difficulties prompted his decision to return to Africa.
Since that time he has called almost everyday to speak and stay connected with Lucian.
I have worked extremely hard to raise our son on my own. I am so proud of the mindful, loving young man he is becoming.
I am also witness to his pain and his need for his father.
It is time for us to travel to Africa so Lucian can see his papa again.
I'm reaching out to our community, our friends and family to help raise the necessary funds to make this trip possible.
My income covers our rent, our food and our daily needs. I simply do not have the money to finance a trip of this nature.
Lucian's father is not able to travel back to the states.
He is a farmer and sends all of his earnings to help me support our son. 
Two roundtrip tickets to Nairobi are between
$1900 - $ 3000
( total cost for both fares combined ) if we purchase them soon.
These prices are going up very quickly as we move towards the Summer months / high season.
Please help me reunite my son with his father. Any contribution is extremely appreciated and I send our gratitude and many thanks in advance.
Thank you,
Love & Blessings
