Childcare/Overnight/Military/Advice

I'm posting about a sensitive topic that has been weighing on my mind. Im a single mom in the military living here in a city where I don’t have family / much support, so with my situation I find myself in need of advice or resources. For instance me having to go to the field for several days, including overnight stays, I'm looking for reliable trust childcare options during that time. While I'm open to paying for childcare, it can be challenging to find someone trustworthy and affordable. If anyone has recommendations or resources that could help, I would truly appreciate your input.
