Small website bug fixes

We are looking to hire someone who can handle small "bug fixes" quickly. They're little jobs, but because our site is "old" (created in 2009), we end up having a number of them that come up over time (for example: plugins that stop working, things that don't format correctly, mobile responsive issues, etc.). On average they will be simple ~$10-20 fixes, however we'll always check pricing and availability with you first for each additional piece of work. Here's the first job we are looking at: It's a "mobile responsiveness" issue. To see the problem, go to [login to view URL] on your mobile phone. Click on the menu and select "Support Us". When you scroll down you'll see when you get to the Donation section, (eg Monthly Donation, Annual Donation, One-Time Donation) it looks terrible on mobile. If you turn the screen horizontal it looks much better, but we don't want to have to tell people to do that. We actually would like to make adjustments to the spacing on both the desktop versions and the mobile versions so that they both look good. (Note: we are looking to have someone we can call on repeatedly over time to handle mini-projects like this and once we agree on the price for each piece of work we will add it as an additional milestone). If things go well, we will also consider you first for some larger projects we have coming down the road in the future
