UK Work Permit : DIY or Hire lawyer?

I have a pontential IT job opportunity in UK. And the employer who is
interested in me is new to hiring foreign nationals.

I understand basic procedure for employers to apply for work permit.

My question is :

Is it still successful for employers to apply for work permit
themselves? or
Is it safer to leave professionals such as immigration attorney
handling this?

Which is the most common practice for UK employers to hire foreign
workers?

Does anybody know?

Hej Dude,

I dont think applying on own will be a good option because so many of
my friends tried the same and got their visas rejected. Try to hire a
lawyer so that you better stay on good chances.
Also let me know any UK employer contacts because i am also looking for
java job opportunities in UK.
