if you want an auto installer for joomla then look for a host with Fantastico OR installatron - I personally favor installatron because they contain more scripts and they update much faster and I have exp with both softwares.
and since you have a small site, any host would be suitable really. Although not all hosts have the auto installers or actually allows joomla so You have to go around and ask around. MDD Host, Innohost, whirlhost, etc. - all good providers and most of them are active here on WHT
I would strongly suggest looking into a web hosting company that does not oversell first off and one that offers shared hosting. The overselling is a big plus because with your website you don't want to have to worry about server loads and dealing with others who might be doing stuff that's not 'respectable'.
There are so many wonderful web hosting companies. I strongly suggest researching the company on WebHostingTalk.com and even doing a Google or Yahoo search will provide you with alot of helpful information. Best of luck and if you need help with anyone else please let me know I'm more then willing to assist you. Good luck!
