I've raised £2500 to Help us have a baby

My partner Phil and I have been together for 3 years, and between us we have 4 beautiful daughters (2 each). We would love to have a baby together, to make our family complete, and join the 2 halves equally.
However, following bad experiences with the mother of his children, Phil took the decision to have a vasectomy 5 years ago, not knowing that he would later meet somebody who would be the ideal mother not only to his 2 young daughters but whom he would love to have a new child with.
Vasectomy reversal is not available on the NHS, so we are looking to raise funds for a private procedure.
We would love the chance to fulfil our dream of becoming parents again, and for all of our girks to have a joint sibling.
