This is a pretty straight forward plugin for most developers. Only variable might be how you want to get the latest price of a stock on the stock market. If you try to automate that, it might take a little work to figure out that automation. Otherwise, most developers on here could do it.
If you want to pay someone to do it, just say so and people can contact you through your profile if you’re interested. There are a number of people on this site that do that type of work. Just depends what’s on their plate at the time. There’s not really a separate place to advertise work for now. Maybe we should create a tag for it and admins can make sure the tags applied before the lock the thread.
