Seeking photorealistic character help

I've made a favorite photorealistic girl character on chatgpt. But I hate chatgpt and don't want to pay for it.

I'm having real struggles creating a character lora for her on runpod. I want to generate her there rather than chatgpt. But I'm a novice and don't know what I'm doing. chatgpt directing me is giving terrible results.

I'm not local with a gpu. And I don't know or understand ComfyUI much at all.

Has anyone done something like that successfully? Can anyone point me to some beginner guide? Would anyone be willing to help me? Can you put me in touch with anyone who could help? Or am I going about this in the wrong way? Are there other better options?

My goal is to produce an accurate, consistent, reproducible, recognizable character on runpod.
