I wish I will have / If only/I wish I would

Hello everyone,
May I say these sentences? Could you please explain the reason.

If only/I wish I would have enough money to buy those shoes.
I wish I will have enough money to buy these shoes next week.

Thank you.

If only I had enough money to buy those shoes.
I wish I had enough money to buy those shoes.

I hope I will have enough money to buy these shoes next week.

Here’s the explanation:

I think that the sentence “I wish I would have enough money to buy those shoes.” is just similar to the sentence provided in your website.

-Future
I hope it stops raining soon.*
I wish it would stop raining.

Please check.
Thank you.

In sum, I could say that:
We should avoid using ‘wish’ with ‘will’, ‘would’
We should avoid using ‘hope’ with ‘would’, could’, even though no example for this provided in your website.
Am I correct?
Thank you.

They are not the same structure. You have used the wrong tense.
Your sentence should be
I wish I had enough money to buy those shoes.

That’s too simplistic as so much depends on the exact context and the vocabulary used.
You would need to use a different tense of ‘wish/hope’ with ‘would’ or ‘could’.

To illustrate, these break your ‘rules’ but are possible:
I wished I could come with you.
I hoped I would have finished by now but I still have a lot to do.
I had hoped I could have saved enough money to buy the shoes by now.
