> 
> Я с радостью помогу. Только работать постоянно **никак не получится**.

I'm trying to grasp the undertone of this phrase. Does it mean:

> 
> Try as I might, working full-time just won't work out for me in any way.
> 
> 
> {or}: Regrettably, I won't be able to work full-time. I just can't make it happen, despite my best intentions to the contrary.
> 
> 
> {or}: I wish I could work full-time, but circumstances don't allow me to.
> 
> 
> 

I mean, rather than showing a strong refusal on the part of the speaker:

> 
> I'd be glad to help, but there's no way I'm going to work full-time.
> 
> 
>

On another note: Can I use "получиться" and "удаться" interchangeably here, or are the two somehow nuanced in this specific sentence?

> 
> Я с радостью помогу. Только работать постоянно **никак не удастся**.
