Native-like or not no. 27 - a longish sentence about Shanghai

Dear All,

This is what a friend of mine who's having doubts as to whether to go to Shanghai or not said.

To be honest, if I go to Shanghai (and I think it might be a good opportunity for me) maybe I won't even have to go to England to get a degree. Perhaps I could do it in Shanghai and if I'm good, if the company will be satisfied with me, they will perhaps pay for my education. If my work here is so disorganized and if my health test results will be bad then I have every reason to leave this place.

There's a number of things that I think should be changed.

• The first sentence, marked in orange, employs the 1st conditional. Now, wouldn't the 2nd conditional be more appropriate here?
• Another sentence, marked in blue, includes a lot of if's I don't know if it's correct to say If I'm good... and if the company will be...
• The same question concerns the part marked in purple.

I'd be grateful for a detailed explanation.

Thank you!
