I think the best option is to send offers to buyer requests.
As you have one 5 star review now, there's more possibility to get another order sooner.
Please send all the 10 offers allowed for a day.
Good luck!
I think it doesn't count under late delivery once the first delivery is made.
So, it won't affect the for the on-time delivery rating.
Please correct me if I'm wrong.
Thank you.
