I've raised £2000 to help fund a new childrens bedroom

As dad of two little children (boy 11yo, girl 4yo) working hard as professional cleaner, I just struggle to provide them with better furniture. I would like to provide them with better quality beds, bunk bed, shelving, wardrobes etc. We would like to do some repairs around whole house (decorating, water taps), garden fence (there is couple of panels in need of exchange for a new ones). We do try really hard to provide everything needed, working hard, keep our house clean, pay the bills in full (there is not a penny in arrears), we just struggle and we feel exhausted. We are non smokers, not drinking alcohol so there is no need to help with bad habits, we need different help, please. Help us if you can. I do my best I am able to. Brave aiming high. Any money funds we start spending is re-decorating children's bedroom, beds, new pillows, duvets and covers, towels etc., if there is any more money coming, we would like to spend on the house to keep all necessary repairs not covered by the landlord. Any help towards buying our first own house and get out of the misery would be greatly appreciated by all of us.Thank you very much in advance. God bless you all
