Advice on financial requirement

[Kokky]

Wife Moroccan with 5 year Spanish residency (work) but is unemployed

I am British born

We have 9 month old baby who was born in Spain with a British passport

I have been to and forth for too long and wish us all to settle in UK now and I cant sustain the travel costs anymore

Prior to May 2017 I was on ESA then between May 2017 and December 2017 I had no income

Since Nov / December 2017 I have been self employed and grossed about 30 k

I haven’t yet paid tax (bit have it saved) but have registered and it’s being dealt with

When is the earliest I can apply for spouse visa?

Is there another way under human rights ?

Any advise of what I need to get the ball rolloning on this ?

May thanks in advance
