What's difference between the following sentences:

Thanks for contacting us.
Existing comments have clarified that it should be 'getting in touch with' or 'contacting'.
'Contacting with' doesn't work, though 'getting in contact with' is possible - I just wouldn't use it in either of the above structures.
I would also change the 'thanks'..
'getting in touch' is informal, so the structure
"Thanks for getting in touch with us"
works perfectly well.
On the other hand 'contacting us' is much more formal & I would prefer to see it book-ended with 'Thank you'
"Thank you for contacting us"
In practice, there is little, if any, difference between the two. Both are acceptable for business use. However, getting in touch with can mean establishing a relationship, while contacting is strictly about the communication transaction. For example, it is possible for someone to get in touch with his feelings or get in touch with his feminine side. On the other hand, contacting his feelings is altogether wrong, and contacting his feminine side would imply a multiple-personality disorder.
