Here in our office we do a lot of work through Freelancer.com
I personally have an account where I take on PHP projects and we have this company account where we outsource extra work that we don't have time to do in-house.
The point is.. we use Freelancer.com a lot. I am always on the go and signing into Freelancer.com through any smartphone is a PAIN. Try sending messages or biding on a project. I am actually quite surprised that Freelancer.com hasn't created a mobile version of their website. These guys are behind on the times.
I am looking for someone to create an iPhone app that will utilized the Freelancer API. Basically we'll pay to develop it and we'll own it. We've created several iPhone apps for clients, but it's not really our bread and butter type work. We spent more time in other specialized areas.
So if you're an iPhone developer and you can create this app for us, let me know. We'd like to get started soon. Additionally - please keep your prices reasonable when bidding. Otherwise you won't even be considered.
