Hire someone to add some features

I would like to ask if it is possible to ask adding new feature(s) to
your application and i will pay for it.

One of major features is supporting multiple company profile with
their logo, name and etc. And when the user try to add new invoice, it
could choose one of the available company.

And also adding a feature that a user when want to add new invoice,
he/she can choose one of the available invoice pdf template ( I see
that this option is available right now and it can be accessed from
setting menu but i need it to be in better place).

I would appreciate if you can give about, how much and how long it’s
going to take?

Any progress on this? I would also like to be able to setup multiple companies on the same instance of Invoice Plane.
