Small issues existing and new websites on subdomains

There are too many small issues with setting up exisiting and new websites: - db tables for the new website which are not made because of sql restrictions (?), - magento extension login page for dealers which does not work, - not being able to approach phpmyadmin from web, - a new "store select" dropdown on all websites which needs adaptions, - checkout proces to payment provider taskes loooooong time (commonly known issue of magento), - dropdown store selector needs updating with different names and also pointing to blog and services subdomains (wordpress), - other sites need dropdown store selector also (wordpress) etc. We donnot know what other issues are comming up after fixing these. Installation is magento 1.4.2. with version based design (no magento upgrades possible). Cloud server, 4GB RAM, Linux Ubuntu latest server version. Apache and nginx optimized. 2 websites live, 1 being setup and could be used for testing. There's enough space on our server to setup a test environment if adviced. Are you in a position to help us out and work without a clear project description but work step to step with us towards solutions? Timemanagement is a key point considering we will hire you on an hourly based rate. When bidding please send me details of time management and communication.
