You could try advertising more, for example, by putting up signs around the neighborhood, posting about it on social media, or having people you know spread the word. You could also try doing it in a different neighborhood that might have friendlier people, or do it in a time and place where there's likely to be a lot of people walking around the area (e.g., near a church before the end of a mass).
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
Rake yards in autumn if you live where leaves fall. Grab a rake and a few large trash bags and go from house to house offering your services. Ask your neighbors what areas of their lawn they want raked and where you should put the leaves, like on the curb for collection or dumped in a wooded area behind their house. Rake leaves into a large pile, then stuff them into a trash bag and tie it closed.
