Custom chart types in PowerPoint

Are there any smart wizzkids around that could find out a way to get custom chart types in PowerPoint?

PowerPoint has a lot of chart types to choose from. However we have even some better ideas/wishes.
We are lloking for a partner who finds an easy way to have EDITABLE charts in PowerPoint,. So just as it works now (or a compatble solution) but then our types. Some examples of the chart types we think about are attached.
Please let me know your thoughts and a fair price (budget for this project is not hard, just because I had to choose something!).
