Clothing brand - Model photos

I need an expert who is advanced in making photo edits look real and someone who is looking for on-going work.

I need advice as to the best route to go. I am a new business with initially a small budget so i cannot afford to pay models, photographers, location, accessories etc for photos. There are 2 options i am looking at but would need you to confirm which you can do and which will have a better result at the cheapest price:

OPTION 1
- Use stock photos but change the models e.g change their hair, change the background, change their skin colour etc so the photos look different - If you can confirm that a reverse image search would not pick up the original photo? Hopefully you can advise on this.

OPTION 2
- I will wear the items and take photos but i am a plus size and i want the model to be a size 8 so the image would need to be altered to take the whole model size down about 3 dress sizes. I would also want a AI generated face put on the model and the hair changed and the background would need to be changed.

Whichever option we chose, there will be 5 different positions of the model posing with the clothing on for example: front on, side on, back, different pose, different pose once we have the base 5 model photos, we can change the clothing using photo editing e.g green, then red, then melon pattern, tiger pattern etc

If you could let me know your thoughts on which option would be best that would be great.

Whichever option we go with, i would expect to see a mock up of 1 item in the 5 different poses to see if it meets my expectations and if i am happy then we can go ahead and complete the different clothing options on the same 5 model poses we already agreed. I am assuming you will be able to 'photoshop' the different clothing items on the base model poses and make it look realistic. To begin with this project will be priced for 15 clothing options with each of the 5 poses and i have a budget of £120 (for the right expert I could be slightly flexible) as my brand gets traction and I generate sales I will need more items and i will have more cash to be able to pay higher rates to a loyal and committed expert who is with me for the longer journey than just this first project.

There will also be adhoc jobs to change the backgrounds for seasons e.g Winter, Halloween, Christmas etc
