Hi Gaelle,
My name is James. It's nice to meet you!
I read your project description, and I'd like to help. I'm a freelance web developer, and I especially love creating WordPress themes from scratch. I'm also able to customize themes to your needs. I do have a couple quick questions for you, though.
1) Do you have the original theme file still? I prefer to develop on my local machine before sending themes back to clients, so would you be willing to send it to me?
2) Do you have a detailed list of all the changes you'd like to make to this theme (color changes, font changes, etc.)?
3) Are there any other requirements that you would like to share?
I'm going to put a 30 days for the time it will take me to complete, but this is only temporary. If you need the theme back sooner than than, I'm willing to be flexible, so just let me know, okay?
If you have any questions for me, please feel free to ask. I look forward to hearing back from you soon!
Best,
James :)
