Honestly, if you want something super simple, just check out Vast.ai. It is basically a marketplace where people rent out their hardware, so you can find some insane deals. I use a NVIDIA RTX 4090 24GB VRAM machine there and it rarely costs me more than 20 cents an hour for image generation. It is super easy to get a Docker container running and you can stop it whenever you are done to save cash. Just make sure to filter for high reliability scores before you commit to a host. You dont need to overspend to get things moving. It works well for my side projects and I have no complaints so far. Let me know if you get stuck with the setup, its kinda fiddly at first but totally worth it compared to a dying laptop.

Honestly, stop killing your laptop. You should look into RunPod RTX 3090 24GB VRAM instances. They are super cheap, usually costing just a few cents per hour. Just be careful with your storage costs tho, those can sneak up on you if you leave data sitting around. Just spin up a container and start generating images. It is way better than frying your own hardware.

If you want something reliable, I have been using Lambda Labs NVIDIA A10 Tensor Core GPU for a while now. In my experience, it handles image generation workflows way better than the cheaper consumer cards. It costs about 0.60 an hour, which fits your budget if you just spin it up when you need it. Just remember to terminate the instance after your sessions so you dont keep paying for the storage.
