Write some Software -- 2

Hi, i have buyed the wordpress plugin: Fancy Product Designer. LINK: [login to view URL] I installed the plugin, you can find it on: [login to view URL] What i want is to modify the module like: [login to view URL] The plugin i installed has some features of it, but the following functions are missing: - letter spacing. If the user adds letter space, this must change on the preview, just like the module on letterblenders, and also it must show on admin when sending the order - The price must change when changing the font size: Example size 1-10: 1 letter = €6,80, 2 letters is 2x €6,80, 3 letters is 3x €6,80 = €20,40 size 11-15: 1 letter = €8,35, 2 letters is 2x €16,70, 3 letters is 3x €6,80 = €25,05 size X ..... size x .... and 17 other sizes.. and this formula must do the same for 3> letters - for each letter it must be possible to select another color, and also it must show on admin when sending the order - It must show the height and width on the preview (see attached file), the first is the width, this must be based on the count of letters: lets say 1 letter= ±12cm, 2 letters= ±22cm, 3 letters =±32cm and go further.. The second is the height of the font size. This functions i described are from the website of letterblenders i linked above, you can check that page to understand it maybe better. If you have questions, please ask.
