How long do you think it will take until the product is ready for sale on the market?
How long will it be until the product is available commercially?
例文1は、「商品の販売準備ができるまでどのくらいかかると思いますか?」というニュアンスです。
例文2は、「商品が市販されるまでにどのくらいかかりますか?」というニュアンスです。
「商品化する」は、the product is ready for sale on the market や the product is available commercially という言い方ができると思います。
「どのくらいの期間」と期間を聞くときは、How long will it be や How long does it take という言い方が一般的かなと思います。
ご参考になれば幸いです!
