Edit some photos of a model for marketing purposes

I have taken some photos of a model and some of our staff, i would like these 'edited' so they look more professional. e.g Improve lighting/brightness and do some cropping. I would like to use the photos taken on a DSLR camera on our web site and social media posts, need some very basic but professional editing done by somebody very experienced with this kind of work. The 1st project will be to edit 30-50 images.
