Employing independent contractors is possible both directly and through a middleman, such as a staffing agency or an umbrella business. Through networking, job boards, social media, trade organizations, and other means, you might be able to find the finest contractors to meet your demands.
Typically, independent contractors carry out their job as independent contractors or as owners of small firms through which they can issue bills to customers. They should then be hired through a contractor work agreement rather than an employment agreement.
An independent contractor could be asked for a resume, portfolio, references, and perhaps a signed NDA before beginning. However, depending on your demands, the hiring process could be different. References from a contractor should be extensively reviewed to confirm the level of service they offer.
