Everything else seems okay :
Family member of a Tier 1 Migrant
If the Tier 1 Migrant is outside the United Kingdom or has been present in the United Kingdom for less than 12 months, each family member of the Tier 1 Migrant must show that he/she, the Tier 1 Migrant, or (for children) his/her other parent who is also legally present in the United Kingdom has at least £1600 to support him/her; this is in addition to any funds the Tier 1 Migrant needs to prove he/she has enough money to support himself/herself.
If the Tier 1 Migrant has been in the United Kingdom for 12 months or more, each family member of the Tier 1 Migrant must have £533 to support himself/herself.
For example, the Tier 1 Migrant has been in the UK for 6 months and is making an application at the same time as his/her spouse and two children. He/she must show that he/she has £1600 for his spouse and a further £1600 for each child, in addition to £800 required for his/her own support. In total the family will require evidence that they hold £5600 in available funds (£1600 x 3 = £4800 + £800).

Make sure you have enough maintenance funds.
I would also recommend providing those calling cards etc as home office will need a proof etc to ascertain that you are in a true relationship.
Good Luck
