Here are my entries. I wanted to focus on the "return" of assets. I'm not sure if you asked for the name to be Twenty4Seven and include 24/7. I can add that if you want, but I think is is a redundancy which might clutter the name. Just let me know if you want and I'll try to add it in, in a way that does not make the name to hard to decipher. Having been in advertising, I also have a question as to the target behind the slogan. Either way the slogan can easily be added, and you probably need a version with and without the slogan. Your feedback is great appreciated.
I don't know if it was already brought up but if I may offer some advice... you may want to rework the slogan. It may hinder your business and really does not work for what you do. Aside from it being a rhyme it does not play to the bank (your client) nor does it work for the person getting a vehicle repossessed since they are not wanting your service. :D
It works if you were a towing company, but you stated that is not what you do. Just a thought. At this point, I'm already out of the contest but thought it would be helpful to point that out. Best of luck.
I noticed that you asked all the other designers to drop the slogan (wise move, but then you asked those that English is not their language for suggestions. You could have asked me, I would have been happy to help even if I was no longer in the running. :)
