website fixes wish list - do you know a coder?

i'll level with ya, i'm an artist and not a coder. i've gotten my site off the ground, and am looking for help getting some issues knocked out that i can't seem to wrap my head around. please take a look at the following list and let me know how much it would cost for you to fix all of these for me, along with a time frame on how soon you can get it finished.

thanks so much, i look forward to hearing from anyone who can be of service!

1) the home page link, category links, and top header banner have an extra "/" at the end of the link.

2) blog issues - need someone who is familiar with blogger.

a) the archiving is wonky. clicking on one of the archives pulls up a separate page instead of being pulled up on that blog page. i also need each post to have a permalink so people can share the link and or bookmark it.
b) images from cell phone posts aren't showing up; there's a path that's always incorrect on those posts. once i fix the path the image shows up ok.
c) the time posted for blog post is a link but goes to an error page

3) would like to have easier paths on the address bar throughout the site and don't know how to change that - for example:

i have: https://www.heartsandlaserbeams.com//index.php?main_page=product_info&cPath=76_83&products_id=290

Ideal would be: https://www.heartsandlaserbeams.com/accessories/1_inch_buttons

(NOTE: for this one, if it's an easy fix you don't have to go through every page to update the paths, you can tell me how you did the first one and i can fix the rest. this will be a neccessity since i'll be adding new pages and products in the future)

4) ssl issues: on every single page i'm getting a popup saying how "some items on the page are unsecure would i still like to view". i don't think that's supposed to constantly be showing up. i may not have set up my ssl properly, currently the https prefix is on every page and someone told me that may affect search engine results.

5) want the middle of the page (currently light grey) where the products show up to be white instead of light grey.
