I would like to hire a Freelance Developer

Dont say Im crazy!!! I have a little store in a little town in SW michigan. Over the past few years Ive had about 80,000.00 stolen not only from the basement and closets but from displays and actually my desk drawers I could never pinpoint who was doing i, until recently. It turned out to be a little old lady...grandmother of 6. Since she broke in (of which I have on video) she would be looking at major charges. Im thinking years in prison. I havent broken the news to her yet. But kind of feel I have to handle the whole situation with kid gloves to ensure im not destroying what could be the last years of her life and her grandkids grandma . Im more concerned right now about recovering lost merchandise. The easiest way I can think of is by getting into her phone. I know, most everyone says let the police handle it. I don't know of too many that wouldnt try to be the "hero" and put someones grandma in jail. Ive gotten to know her situation over the years. I guess Im a little too understanding too as I've Caught about 8 people stealing but none that broke into my shop and haven't prosecuted one of them...as most are family and/or friends. I know she would deny it til the end. Im still in business. Ive had a lot of her help keeping it together and stocked. Ive confronted her son. I didn't fill him in everything. But he got the gist. He told me where she has some of it. But a good portion was sold. I would like to recover the sold stuff before I confront her and get the stuff from her. The easiest Way I can see would be to get into their cell phone. Items Were Taken As recent as last night. So It Would need to be done asap. I am an old timer when it comes to computers software. I cant even make a good judgement on what software to purchase. so I will buy the one of your choice and you will take care of the rest. If you need help I will coordinate with you. Job specifics, pay, proof i am not a stalker, will be relayed to interested parties. Thanks!
