I need a fundraising expert

We have purchased a large new building in shell and core condition. When it is fitted out ourselves and nine other organisations, each providing a critical service to migrants and refugees will move and occupy it as our main office. The plan is to create a community hub and a one stop shop service for migrants and refugees in North London. We have a budget for for a basic building outfit but to fully meet the needs of the other organisations we need to supplement it. The aim is to make up the shortfall by bidding to other organisations and charitable funds. We believe our chance of attracting funds is good. The plight of migrants and refugees has never been more parlous. The hub potentially represents innovative and sustainable improvement in the delivery of services to a vulnerable, isolated and needy segment of the community.
