I want to start advertising online for my auto detailing business?

Spend that money on internet advertising, not the site, a decent free host with a custom business domain name id probably enough for a relatively low traffic site with no online transactions.
Be prepared to lose money in testing before you eventually come up with an ad sales page combination that is profitable. Both Facebook and Google have first time ad users. perhaps $30 for Facebook, and Google gives a $100 bonus after a $25 deposit.

If you are trying to attract free traffic it may take a lot of honey, have content that appears to cherry car fans, perhaps galleries of ultra detailed cars at auto shows, you have to write a fair enough as well to match up with search phrases that search engines get.

Again free business directory sites, Google/Bing/Yahoo local search listing pages are all pretty important for connecting with local searches, one point for your site design, a fair number of locals seeking businesses do it on mobile phones, something like a "responsive" Wordpress blog themes that adjust the pages to match the viewers device can help make the best impression with mobile web surfers.
