Regarding wide band HF transformer design, see topic here
I hope the links given still work!
I think Sevick's book is best and the above papers are of good value too.
If it not what you are looking for, than please be more specific.

It is usually cheaper to buy a ready made transformer than to make one yourself. At one time, and possibly now, the transformer companies charged less for a custom designed one than a similar standard product.

You do an serious error. Primary and secondary inductances are not calculated as you mentioned.
The inductance values are depending on frequency of interest. At least minimum values of inductances
will define minimum frequency that you may use for the transformer.
For more information look at equivalent circuit of a transformer.

You should find out the primary inductance of the transformer. The formula relating inductance and power applies.
P = 0.5 * L * I^2 * f
P = power
L = inductance
I = current
f = switching frequency
