Suggestions for a server optimization guru?

I'm looking to hire someone to help me optimize my server setup (Linode VPS, 4gb) where my knowledge is weak for a Xenforo install. Sorry if this is the wrong place in the forum to post this. Really I'd like to hire someone for a few hours of work to help me make sure everything is set-up right (I'm guessing updates will be suggested), make and implement any recommendations, and help get my server ready for a launch.

Please reach out if available with price quotes and your background in this kind of work.

Ubuntu 12.04.5 LTS
mysql Ver 14.14 Distrib 5.5.46
PHP 5.3.10-1ubuntu3.21 with Suhosin-Patch (cli)
memcached 1.4.13
xenforo 1.4.2
Elasticsearch 0.90.7

I've got a number of performance related add-ons, but they generally only impact large active boards. Otherwise XenForo itself doesn't require tuning except for setting up a cache and ensuring php opcode caching is enabled.

MySQL 5.6 (or MariaDB 10.x) are getting to have sane defaults, which makes for a nice change. But you still want to get someone to check.
