Hi, David:
My name is Baltasar García, and... I am Spaniard! I am therefore able to complete a presentation for you about Spain, Madrid if you like. Actually, we can choose whatever theme you prefer (sports, weather, turism...)
I am also a lecturer in computer science (since 1998) and I have a good background about creating presentations, so there is no problem at all, whether you like it in (LibreOffice) Impress, (MS Office) PowerPoint or plain HTML.
¡Muchas gracias, y espero saber pronto de ti!
Regards,
Baltasar
