Eco-friendly sandals/flip flops wanted!

I am looking to work with a sandal/flip flop manufacturer to develop different lines of eco-friendly sandals for my company.

I would like to incorporate several specifications/features into the sandals including:

1.) Interchangeable straps

2.) Various patterns and colors

3.) Eco-friendly materials

4.) My company name and logo on various parts of the sandal

5.) Size and company website engraved on the bottom

If you are a manufacturer and think you can help me develop a highly specified sandal/flip flop, and can do it with eco-friendly materials. Please contact me! Thanks so much!
