There are a few people on here who have used them and are currently in the process of moving over!!! It was only by chance that we came across them on the net we have met with them at Birmingham and saw how things are done they are very professional and if you look to see what partnering company's they work with they are quite big names, not only do they do all the leg work in finding you a suitable job but they help you with everything needed to go with it they are always there at the end of the phone or email and will help you with the whole move not just finding you a job and getting a visa. I hope this helps you I know it's a daunting process we've been there and made the decision to use live the dream.
Hope everything works out for you.....
good luck in your decision
