You can always look through craigslist. I know they're worldwide, just don't know how commonly people in your area post on there.
You could also solicit a responsible teen in your neighborhood to pet sit -- just pre-measure the food and any dosing, and write specific instructions and "what ifs". I, myself, hired my neighbor's 12 year old, who I trust 100% to look after all my pets. I've even been gone for 2 weeks, and she did a great job! Everything was written out and premeasured. Even top offs weren't a problem before I got my ATO. What little I paid was actually a lot for them, so I saved money with her than if I used a professional. Test them out for a weekend to see if they handle it ok.
I doubt the vibration will cause that much harm...but it might stress them. Not sure. I'm also about to sand the drywall under my tank. I'd be interested to know what people think.
