Apps to implement into Wordpress Website

There are two projects. Project #1 will need to design an app which allows the user to design a certain type of beauty product. The process will include uploading photos, resizing, cropping, colors, drawing, etc. This app will need to be implemented into a Wordpress site. I will give you another website that has a similar app to get a better idea. Project #2 is an app that counts the number of words that the visitor enters in a text box. This app needs to automatically take the number of words in the text box and multiply it by a dollar amount (ex. 15 cents) and give a total payment amount. The user then needs to have an option to pay this amount. These are not large projects. Please email me with your questions. I'd prefer a fixed price but if you insist on an hourly budget, we can work that out as well. Thanks, Emmanuel
