i hope someone can help us as this is a matter of some desperation.
Here's the story to put you in the picture:
I met my son's father whilst travelling in West Africa in 2002. We fell in love, and i fell pregnant rather quickly. I was married at the time and initial joy about having a child turned into panic and depression and i left Africa to think things over over here in the UK. I spent my pregnancy here, had my son. All the while his father and i were debating and finally consolidating our relationship via phone and email. He saw his son for the first time when he was 9 months old, in Switzerland. He was able to get the visa for switzerland because he used to live there with his former wife,but divorced before he was granted a permanent visa.
I am a single mother with the usual struggles that lone parents have, meaning that i am dependent on a number of state benefits. I made the choice to not go back to work during the first 2-3 years of my child's life.I am at present seeking a job.
I got divorced in june 2004, and tried to invite my son's father for a visit to the UK in March 2005, his visa was refused on the ground of insufficient funds, although i had borrowed a large amount to make it possible.
How am i as a single parent supposed to create a situation whereby the law will grant the reunification of a father and son? How am i supposed to earn a fortune to prove that i can sponsor him,when in fact his mere presence in our lives would make financial sense in itself, as it would make fulltime work possible for me initially without the burden of £1000 worth of childcare per month?(if i must not take recourse to public funds it means that i cannot receive tax credits either, i presume)
Any ideas? We are desperate to be together, our son who is now 3, is asking after his daddy, whom we visited in Burkina Faso last Christmas, and we feel so unfairly treated by the system for keeping us apart.
Any suggestions, new ideas, clarifications are welcome

Thank you
