Frankly speaking, I do not know OCalm.
Checked what it is. Think I should understand how to make proper code.
My strong experience is in Linux, kernel, drivers, video playback, C, C++, PHP, bash, Perl, Python, Javascript, Ruby, SQL optimization, MySQL, Postgers, etc.
Used but not oftenly: Lisp, Firebird, Berkeley.
I do not know the volume of work. If it will be some several simple changes (not total revision of all SQL-s) bid may be negotiated to be lower.
If you will not find experienced OCalm programmer for low price, I would like to do this job.
It is really interesting for me.
Environment (ocalm packages) I found on my OS (Gentoo Linux).
