Hopefully it won't be too late for you to hire a professional after you have asked your neighbor's son who visits twice a year to create your logo, website, or online presence. Poor Madrid. Did you read the story about the fresco that was ruined by a well-intended woman in her 80s who volunteered to restore the fresco, "Ecce homo" of Jesus. Tragic, but a perfect example of you get what you pay for. Hard lesson, one that cannot be fixed.

Ms. Giménez said she had worked on the fresco using a 10-year-old picture of it, but she eventually left Jesus with a half-beard and, some say, a monkeylike appearance. The fresco’s botched restoration came to light this month when descendants of the 19th-century artist, Elías García Martínez, proposed making a donation toward its upkeep.
