Hello
I have read your project description and would like to write this add-on from you. I saw how [login to view URL] works and can implement this for you.
I also saw how [login to view URL] works and understand your needs but have a question... Do you need to charge an additional fee for each attribute or do you just need the attributes shown as you described?
For the text as an attribute, do you need to show a preview of how the test looks on the product?
As for myself, I have over 10 years of experience with OSC, PHP and MySQL. I actually even built an online marketplace using OSC and you can see how heavily modified this marketplace is at [login to view URL]
Thank you,
Danny
