Well, all of those gigs were for agencies I used to work as a developer. I was not interested in taking another fulltime project anymore (I was migrating into farming) and those code reviews, pre-sales (and I also did tons of interviews) was offered as a compromise. I don't know how you can get those kind of jobs, but I don't think they will outsource it to some person over internet without history of working together. Those gigs really affects the income of those agencies so they are probably very careful to hire for those roles. I think you should ask around the people you are working with, companies you worked with and so on. I think most rapidly growing agency is in desperate need of people like this, especially if you work for them just for hours per week so you are not destroying their cash flow.
