I think it's gimmicky. I as someone that doesn't personally do contracts at this point, I don't think it's a good idea to have "no contracts" on your ad. Cheapskate people that will try and get you to come one week, not the other, maybe not this week since ce it isn't too tall, etc. That's who you'll attract. You want to know that the client you worked to get will provide a set minimum revenue for the year. Especially at the beginning of the season. Some guys have their clients prepay the entire year. Some guys tally up a year of service, and divide by 12 equal months. It's a bit cheaper during knowing season, but allows them a steady monthly budget and provides you with income during winter. Whether you line those up with written or verbal contracts, or however, it's still a form of contract. You will limit your growth, even as a solo if you don't figure out how to get a client and maintain that steady revenue. And then be able to project for the next year based on those contracts.
