I've finished Vex's and Delvin's side jobs for Windhelm, Markarth, and Whiterun. The only city I have to do quests for is Solitude to get the achievement, but neither Vex nor Delvin will give me jobs in Solitude. Is this a glitch, or do I have to get Solitude quests from another person?

I posted a thread about this earlier. I didn't know what exactly the requirements were for this achievement

Cheers

Im also having a problem with the thieves guild. I accidentally sold all the armor they give you and cannot find it in any stores. So I cant find it to give to that girl and finish that quest. Am I screwed?
