Help translate these sentences into Japanese (pretty basic)?

Question:

1.) In order to control the Daimyo, the Shogun forced their wives to live in Edo.
2.) They had to visit Edo every other year.
3.) The trip was expensive so they couldn't afford weapons.

Kanji with furigana or all hiragana please.
Also no online translators, I could do that myself ;)
Thanks so much!
