I think one of the points in favor of sortition is precisely that, at least most of the designs that I've seen, tend to call for ad-hoc assemblies to discuss particular issues. To participate in these you tend to be paid and they tend to meet say 2 times a month (on the weekends) for 6 or so months. The whole point of the citizens assemblies is to get rid of career politicians. There are many designs out there but I think almost all of them that incorporate permanent assemblies focus much more on the building of a structure rather than the building of the careers of the individuals. That is to say, they incorporate rotation in these bodies that "keeps the blood running" in a way. The point you bring up about people having to leave their careers to become politicians is exactly what these sort of proposals try to salvage. I think right now we are kind of in a trying phase where the main question that's trying to be answered is the following: is it possible for ad-hoc assemblies to achieve similar or higher quality of deliberation as permanent elected bodies? And so far the answer is actually yes. If you're interested, there's actually a lot of info out there but reading stuff that Helene Landemore and Claudia Chwalisz have written is a very good start. I'm not really an expert in this topic but they are!
