Hi there,
First off, when you first open up the site it looks really good. Very professional and eye-catching.
My thoughts pretty much echo the other comments, it is not immediately clear what you do. Although, in your defence If people come across your site it is probably because they are looking for your type of service.
I think your strap line should better reflect your service, something like, "Kendlebell, the perfect answer to your call handling needs" or alike... just add a bit on to your already good line.
Apart from that and maybe making sure all external links on your site open up on a new window (you don't want to lose browsers do you?) and checking a few grammer areas (who am i to talk about grammer?), as I said, I think it looks good, real good.
