Pc monitor and tower (Shepshed LE12)

I run groups for our local community and have no form pc monitor and Tower.we have to do a lot of paperwork for our members etc. The groups run on donations only and just can't afford a pc set up.The community lounge that I run is for all the community to Drop-in have cuppa and a chat. Plus we open up in winter times so th community can get warm without using their gas or electricity, being how the prices have risen again. I hope someone out there could help us. Thank you
