Finances for dependent Visa

[mustang390]

Hi I got ILR and I want to apply for my Wife and Twin Baby girls.

My Wife was with me here in the UK on the spouse Visa and we had twin babies in 2011, then my wife Moved back home with babies as it was difficult for us to manage (u know first time parental experience with twins is always Double trouble) and Wife's Visa ran out this year in March.

Now I want to apply for my Wife and Babies again. So My question is

1) WHt type of Visas do they need ?
2) Do I need any minimum Salary to be shown to support 3 dependents and how much is that going to be ?
3) I am self employed wht documents do I need to show ?

Regards
