A non-jew would be a bigger issue, there is a shaila of amirah l'akum. There is no issur called "amira l'yisroel", I don't understand how there can be a problem to ask a jew to do something he is allowed to do. It's like someone who was mekabel shabbos asking someone who wasn't to do melacha.
There is basically two aspects to be dealt with when talking to another Jew regarding melacha.
The first is zilzul Shabbos, which is dealt with in our case because it isn't Shabbos. However, regarding (for instance) YT Sheni, you cannot talk about something that is a melacha for you even though the Yisrael is muttar to do melacha even on your behalf. (You can hint and you can benefit if he gets the hint.)
The second is lifnei iver. This applies if the reason you are not acting applies to the other Yid as well. In our case, the other Yid is in EY and it is not Shabbos. However, if (for instance) you believe that opening the bottle is a deoraysa, you cannot ask another Yid straight out to open it for you. (If you hold it is a chumra, and he has his Rav who matirs, it could be you can.)
So I cannot see the problem with telling another Jew before Shabbos to do something that is muttar for him, even if for you it would be ossur when that time comes.
