They Are pretty decent Geo domains usually sell , since you are targeting Canada you'll have to outbound and contact Canadian accounting firms small ones located in Saskatoon for example or you'll have to wait for a bit long since the domain is pretty niche and geo specific . Toronto Job agency also could sell as well .
As for OriginalAnalyst.com is a good name you might want to hold onto it for a year or two maybe 5 years to increase it's value and justify a selling it for a higher price maybe xxxx range . I recommend to add a make offer to evaluate whether the offer is worth it or not for you . Same goes for the other two except if you want to sell them quickly you'll have lower the price and make it affordable . If your goal is to sell them for higher profit then it's going to take a while before the right buyer comes .
I recommend focusing on two word domains or one :
. Relevancy
. Usually domains with more extensions taken tend be more valuable ( check dot dB, Domainleads.com)
.The Age of the domain is also a factor since newly registered domains are in the sandbox phase and don't rank high by google so they are less favorable , holding a dropped valuable hand reg domain for years will increase it's value.
. Use Namebio and analyze the keywords .
.Focus on making cashflow as a beginner.
Good Luck and keep learning .
