You can also just hire someone who's smart and willing to learn. I mean web development isn't that hard. I know everyone wants to hire someone who meets every single one of their many requirements (we've all seen the job ads), but realistically how long is it going to take a smart developer to pickup say Javascript + whatever APIs you're using? A few weeks? You could easily spend months trying to find the perfect hire.
It's not that hard compared to other skills. Anyway web development includes a lot of stuff, and you can really go low level if you have to implement algorithms and address scalability.
