Build a Website

1: I have site translated using sub-domains and each sub-domain has Joomla CMS installed with separate DB. Now, I'm trying to move from example: [login to view URL] to [login to view URL] but, when I make that switch, the main page works ok but inner pages giving me 404 error so I need someone with extensive experience to look into this. 2: I need to make changes to meta title 3: make changes to currency trending parameters (basically display % value based on daily changes if it goes up or down EXAMPLE: USD to EUR up by 00014%) I already have this setup but in different section 4: Replace old chart using Google [login to view URL] 5: Place relnofollow values into some URL's 6: create a small script to do the following 1: Say we have conversion for whole amount excluding cents example shows $1 usd to eur, etc... to display link in content area (I'll explain where) a: [login to view URL] to display a link for B (2 usd to eur) b: [login to view URL] to display a link for C (3 usd to eur) and A (1 usd to eur) c: [login to view URL] to display a link for D (4 usd to eur) and B (2 usd to eur) d: [login to view URL] to display a link for E (5 usd to eur) and C (3 usd to eur) e: etc... 2: Amount with cent values example $1.25 usd to eur or $2.42 usd to eur, etc... a: [login to view URL] b: [login to view URL] c: [login to view URL] d: [login to view URL] To display <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"> in header section also Please PM me if you have questions.
