Hello Haddion! It seems as if what you and your wife can contribute would be a perfect fit for our semi-casual guild!
The only difference is that we can provide you more than what you are looking for! (which I do hope is a good thing :D) We regularly get 40k seals per week and are in Bracket 3 of GW, and happen to have two open spots for your taking! We also complete 8+ Legendary Tasks per week (which is a lot of sweet loot)
We are a friendly guild that promotes living life while getting all of the benefits from a high level guild at the same time. We like to keep it as casual as possible while pwning it up and having a good time in guild chat!
Feel free to check out the guilds requirements in more details in the link below. We’d love to have you and your wife as future long time members of our long standing 3 year guild! 
PM me with any questions and hope to hear from you soon!
