A typical service includes creating original images from written prompts, iterating on results based on your feedback, and delivering final files in your required format and resolution.

Midjourney, Stable Diffusion, DALL-E, and Adobe Firefly are the most widely used platforms. Each has different strengths in style, realism, and creative control.

This depends on the freelancer's package. Some services include multiple variations so you can choose the best result. Check the service description or ask the freelancer before purchasing.
