Iconmoon font customisation

I am looking for a designer to convert a series of icons we have created in Illustrator into iconmoon format. Please find attached screen grab, unfortunately this app doesn’t allow me to upload the illustrator file. Basically it is for all of the orange icons above, including the icon at the end of our logo of the house incorporating a stylised question mark. 6 x icons at present. What are your costs? What are your lead times? We will be using these on our Wordpress website using a theme template purchased. Which includes a prebuilt selection of iconmoon fonts, unfortunately some of these don’t cover all our specific needs, hence why we have created customised versions in Illustrator as a starting point. Unfortunately the iconmoon instructions are currently beyond our present technical knowledge regarding customising our own. I also underhand there is a way to build libraries of existing and customised versions for reuse and ease of searching and storing. Have done this before? Looking forward to your response.
