Developer needed for additional Matrix theme customisations

I'm webmaster on a client's site that I implemented about 4 years ago. I developed a bespoke customisation of Matrix for it and it works just fine.

However, I still need a few tweaks making to the theme, as follows:

1) Jump Pager on Album page showing all page numbers, not just first 6 then ....
2) Removing/hiding 'Add to Cart' sidebar blocks on static html pages
3) Time/Consultation regarding current security and migrating to v3, as we're currently:

Gallery version = 2.2.3 core 1.2.0.5
PHP version = 5.2.6 cgi
Webserver = Apache/1.3.34 Ben-SSL/1.55
Database = mysqlt 5.0.51a-log, lock.system=database
Toolkits = ArchiveUpload, Exif, Getid3, LinkItemToolkit, NetPBM, Thumbnail, Gd, jpegtran, SquareThumb
Acceleration = none, none
Operating system = Linux infong 2.4 #1 SMP Tue Dec 18 22:34:10 UTC 2007 i686 GNU/Linux
Default theme = matrix
gettext = enabled
Locale = en_GB
Browser = Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.0.1) Gecko/2008070206 Firefox/3.0.1
Rows in GalleryAccessMap table = 553
Rows in GalleryAccessSubscriberMap table = 7557
Rows in GalleryUser table = 14
Rows in GalleryItem table = 7554
Rows in GalleryAlbumItem table = 56
Rows in GalleryCacheMap table = 0

Please PM me with estimates and availablity. I'm aware the first two are simple coding tasks and shouldn't take that long if you know what you're doing.

Thanks in advance
