Virtuemart theme additions & a product compare

I have a joomla/virtuemart product catalog I am building. The products are not 'for sale on line' just for display for our customers. I have a template I purchased from The vm theme I used is from [login to view URL] and it is nice but missing a few things that I need. However, I do not 'have' to use this theme if it would make this job easier and or cheaper. Here is what I was hoping to have: 1. Addtional tabs This theme has tabs in it, but are missing a couple of tabs that I would like to have included. Currently it has tabs which include: -Description -Related products -Recently viewed (which shows when you look at another product) What I would like to have he first tab name Description changed to the word Features. I would also like 3 more tabs there including: -Specifications (and this tab should have a table which includes - Weight, Exterior Dimensions, Interior Dimensions - see this site (scroll down and you will see the table [login to view URL] )): -Ask A Question (this should be like the Ask a Question about this product link that opens to mail) -Send to a friend (again this is part of VM but this template doesn't have it) If these tabs cannot be made from scratch (instead of adding to the current theme I'd need to know that). 2. Product Compare I need to add a compare products. The -only- joomla extension I have found that does this is [login to view URL] product compare. I haven't purchased it as I still haven't figure out a lot of how VM works yet. In particular what Product Types mean or how to use it for example. The compare I need should be like this: Here are 2 sites that have similar to what I need: [login to view URL] Using this site as an example I can compare 3 safes and it opens to a compare page (table). I need the comparison to be on the: -Model -Category -Manufacturer -Exterior Dimensions -Interior Dimensions -Interior Storage -Fire Rated (yes/no or rating type) -Burlar Rated (yes/no or rating type) These are the things I'd like to know if they can be done. I can purchase the product compare myself for you if needed to be installed. I can also send you my VMJ theme if you need to review it to see if you can extend the tabs from the existing theme or have to start fresh. I do not have a big budget. We are a company of 5 people (a locksmith company). Depending on cost is will determine whether if everything above can be done. If absolutely necessary I can try to go a bit more for the bid.
