We need our logo tweaked

We our a small Celebrant Company looking to expand our business with 'Naming ceremonies.
We have a design in mind (attached) but it needs some tweaking and we need to be able to have versions for print, web and email signatures.
We like the logo we designed using AI but we would like the strap line "Naming Day Ceremonies for Everyone" to be in lower case and the Company name "Welcome to the World Celebrants" to be the same size and all upper case. We need the font to be a free one and if you know of any that are softer and more engaging for mothers and families that would be fine. We would like the falling baby sock to be a buttermilk yellow, the rest in mono.
We would also need the elements separately so we can use them for different purposes. (pantone refs, font names etc).
Many thanks.
