coder to do some wordpress modifications

I have quite standard Wordpress installation with Woocommerce. I would need someone to create some customizations for Woocommerce and or theme. We are creating products using api, we only upload image and don't write any descriptions. Those will be done manually later. so what we need few examples: We would like to show item locations on map. Unfortunately vendor fields are missing address, so we would need some small implementation to that. We also have problem with product images that there are both gallery and featured images, where as we would only like to show one image per product on default. Theme takes gallery image but admin view takes featured image in list view. So if you have suggestions how to create those and let me know if you have experience with wp + woocommerce + themes. It helps if you have done wordpress plugins before. Please state your experience with wordpress / woocommerce / plugin writing or bid will be discarded
