fix my Wordpress website

update plugins. update woo commerce. develop code or find plugin to allow me to change shipping costs myself. I have custom shipping cost needs which have been custom coded, but I need to be able to change them myself without getting into the code each time. if we can find a plug in great. if not, I need code written to give me what I need. I also need a plugin for making pick list for multiple woo commerce orders, so we can pull everything at one time, so need a multi order pick list. a few other fixes here and there. I am also looking for an ongoing relationship with someone to keep my site updated and running smoothly. btw, site is www.pamelabarsky.com
