working visa in Peru (Lima)

Hi,

I am looking for a working visa for Peru to set up as a sole trader. I hear that it is possible to start an SAC and then sponsor yourself to enter the country, but would like to hear this from a (reliable) lawyer or accountant.

any advise or stories on how people have achieved this would be great..

I am fluent in Spanish, so this is not a problem when recommending people.

saludos,

Lachlan
