Can someone help with this sentence involving double denial? 無いこともないのですが


> 実は全く手段が無いこともないのですが、それがあなたのためになるとは俺には到底思えません

Can someone explain 無いこともないのですが? It's a double denial from what I can tell. So
does it become this:

> Actually it's not like there's no method at all, however I cannot possibly
> think that it will be useful to you




Yup!

The double negatives cancel to make it affirmative. It does show the writers
hesitation in telling the listener about them or to use the method at all.

手段が無いことないですが --> 手段がある
