Can I pay you for custom TidByt app development?

I backed TidByt and had a sense it might need some help getting to be useful for my needs, so I allocated some budget for custom app development when I bought it.

For a simple app utilizing standard available APIs on the internet, how much would I need to pay a developer to make me an app?

For example: the ski forecast app is great, except it’s Epic only. I want an app that looks/works similarly for the one mountain I do ski at, and whose data is available via API. Will you develop this app for me? How much would it cost?

I’d also like to have developed for me a simple ocean buoy reporting app that shows dominant wave direction, amplitude, and period using the (i think) publicly accessible data: NDBC - How can Realtime data be retrieved from the NDBC web site?
