Keep my boy near his Dad

My son was abducted by his mother 2,5 years ago over international borders. It took me 6 months to return him to the country of his birth.
Her parents are millionaires and are funding her and (after years of paying lawyers, mediators, psychologists, courts, lawyers, and barristers) I am nearly broke, as I have to fund myself.
She has made serious claims of assault against me (with regards my son) that have been proven to be untrue by the authorities and that she admitted under cross examination were made to further her court case.
She blocks me at every turn for more access to my son.
I am fighting to keep my son near me and she is trying to take him away overseas again. 
If she wins, I will not have the ability to see him.

Any money raised will be spent solely on legal fees.


(For my son's privacy ii have not named or uploaded a photo of him )

I think its also important to add that I am doing everything I can to do this myself and that I don't lightly ask for assistance. I work as much as I can and to say I live frugally is an understatement. I pay my child support, spousal maintence, the mortgage I was left to cover, the added mortgate interest from the money that was improperly removed from the joint mortgage. I also pay the council rates and all my other bills such as the bank loan I took out to fund legals. 
Also my family have helped me as they can.
If you have any doubt that I am doing as much as I can for myself, then just ask.
