It’s important to know that MOST clients will not be engaging your services as they are also getting quotes from other videographers. They consider options such as their budget, your equipment / expertise and portfolio.
I personally have not had much luck from getting GOOD clients on craigslist / listing sites, because these people have high expectations not = to their budget. These people wants high quality for costs they are paying.
Personally, I have been working on property markets, food and media tastings more often recently. I feel there is a higher chance for client acquisition in this field because there is a need for marketing materials.
To get clients like these, you can start dropping text messages to nearby property agents and restaurant owners (small ones first!). Personally text them if they are interested.
