This concept of "startup recipes" doesn't work very well in practice.
A hypothetical new soaper asks for a newbie recipe. Someone suggests a well balanced recipe. New soaper responds they won't use animal fats or anything palm.
Someone else suggests another recipe based on those criteria. New soaper responds with another objection that the fats suggested are impossible to find or too expensive. And so on.
It is hard to know how to respond, so many just don't reply. That creates yet another problem because new soaper then gets the feeling they are being ignored.

You have a very short list of fats you say you can use -- olive, sunflower and maybe some coconut. These fats are low in palmitic and stearic acids, which are desirable fatty acids that build longevity and hardness in a soap.
You're pretty much limited to some type of soap that's mainly olive oil. Try 100% olive. Or try a 10-20% coconut oil with the balance being olive.
If your sunflower oil is a high oleic type, you can substitute it for all or part of the olive. I'd use whichever one is cheaper.
If the sunflower is not a high-oleic type, then I'd limit it to no more than 20% of the total fats. My preference would be 10% or less. Add to that coconut oil at 10-20% and the balance being olive.
Use these guidelines to create a recipe. Try a small batch (500 grams of fats total), let it cure, and see what you think.
No, I have not said anything about the NaOH and water weights. It's important to learn to use a
soap recipe calculator to calculate these weights. Reasonable settings would be a 2:1 water:lye ratio (33% lye concentration) and 5% superfat. If you want us to double check your work, post your recipe here and ask for someone to look at it and verify the numbers.
Even if someone hands you a recipe complete with water and NaOH weights, you need to check each and every recipe with a
soap recipe calculator for correctness. Don't blindly trust anyone's numbers -- do the calculations to make sure the soap will be safe.
