Biz, my recommendation for you is to do the following:
1. Since you need a receipt, your insurance provider (like mine) should provide a list of approved direct billing establishments. Look at the names reviewed on the forums here and match it to your insurance provider's list. On mine, when I last looked into the southside clusters, I found that GE is not on the list but some of its neighbours (all reviewed here) were. Your insurance provider's list will likely differ from mine. It only takes a minute or two to scan through the list and look up familiar names. Chances are that they are legitimate businesses (and look the part) if they are pre-approved by your insurance provider.
My accountant asked me once, how come you use so many different places for massages and physios? "Oh, these were all preapproved by my insurance and I just go to whoever can fit me in"; a very easy answer for whoever may be nosy. You may need a different reason, i.e. it is close to work, it is close to home, my friends work there; which part of the city do you want?
Do you like a place with bright pink signs facing a business street? Do you like a place on the second floor of a discreet building? Use Google Map to figure out if you like the outside. Using a few south side places as contrasts,
-Rosewater & Meridian both have bright signs and face a busy street,
-GE ground level in a busy complex with many other businesses, parking lot and neighbouring cafe can be very full and busy,
-Blue Sky is just up the road on the second floor of a plain white non-describ larger commercial complex,
-Strathcona is a couple blocks away in a strip mall facing a deserted industrial street,
-HK operates out of a private house near southgate.
As I am single, I personally could care less who sees me walking in and out of different establishments, if you care, you may want a more discreet location like Strathcona's or HK's. Labella is out east is also located in a more or less deserted industrial part of town. The opposite would be a busy place like westend's Ting Ting or Xiao Ping, they are so busy that you are almost guaranteed to run into other customers inside; don't worry, we are all there for a great massage; LOL, even I am uncomfortable walking pass the busy Earl's patio for a massage.
2. If the place is reviewed here, chances are that certain individuals (may be not all) there may provide hand releases or may be a little more. The perfect individual for me will differ from the perfect individual for you. I like to pick on MassageRook, the perfect girl for me will likely be way too skinny for him, we are all different; try a few and narrow it down. I can just imagine what MassageRook thinks of my all-time-great goddess Vivian, "too skinny", sigh... Vivian, please come back.
If you find an establishment on your insurance provider's list and need a masseuse's name or two to get started, I am sure many here would answer a DM or two with names to get you started. Some basic questions will need to be answered, do you like them thick or skinny, do you like your massage hard or sensual, do you like asians or not, do you like them young or older, do you like big boobs. Can't even start to answer questions without know a little bit of what you want. If you know what you are looking for, DM me and I may be able to get you started; I am not an expert on all of the different establishments, just the few I frequent.
A sure fire way to get yourself blocked is by asking "how much will it cost to f*** her"; don't ask prices and don't expect "f***ing" at a semi legit place. I am not saying things beyond a HJ do not exist in a semi-legit but it is rare and it will take time, sometimes A LOT of time/$$$, to develop that relationship. Just go with the right expectation and you will enjoy yourself. If you want more than just a HJ on a first visit, I would recommend looking into a AMP or a micro and an incall.
