Looking for new ideas for my home business

Lately I have been wondering how I can improve my home business. I know what people are looking for, but getting that takes time and is expensive. Opening hours are an issue for many because it is weekdays in the evenings. Adding more photos of products to my website will help, especially if I do not have any. Somebody mentioned to me to do more marketing, but that is expensive as well. My website also needs to get a cancellation and review system.
