Hello Jackie and welcome to the forum. I don't know of any company that specializes in short term adult companion ship. However there are several possibilities that may help. 1) is to get an alarm company that deals with real time security and who can give you a panic button that you wear as a pendant. You push the button and they respond as you have instructed them. (from have a neighbour come over to calling the police) . They can also alarm your house so that any intruder automatically triggers both a response and a verbal message through a loud speaker that help is on it's way(thus hopefully scaring the intruders away).
You can google security and alarm companies, I don't know which is the best. Alarm Force does have a good website that explains a lot of options, but I have no idea how good of company they are .
https://www.alarmforce.com/security-systems-home-and-business/ or you might try a companion care service like:
http://www.tlcchomecare.com/ Once again I know nothing about that company, I just googled companion care. They offer up to 24/7 service, but I have no idea about their rates. You can google find other companies, by entering such things as companion care and where you live.
You might also try dialing 211 and asking them what may be available. 211 is a free service and operates much like 411, except that it deals only in services. For example if you asked about peer support groups , the MDAO(providers of this forum) name and # would be given to you. They can do the same for any type of service. I tried them on line and I got a list of about 9 places depending on where you live, but half of the battle is trying to decide what name to enter to get the best results (ie companion care, vs just companion) . The 211 operator should be able to help you.
Please feel free to keep posting Good luck and Take Care. paul m
