Who can help me?

Good afternoon. I am a mother with two children who was forced to leave her home in Ukraine because our country is being bombarded with rockets every day. I appeal to those who understand our grief and who are ready to help. Looking for a rental property in Cardiff with 2-3 bedrooms. Willing to make payment 6 months in advance, also have a guarantor living in Cardiff. I guarantee decency and timely payment. Be supportive of our grief, help us find housing. Also ready to consider rental options in other cities.
