Integrate PWA and CCGV module on osCommerce shop + more

The store URL is www.glass#$of#$venice#$.com (just remove the #$). This is a heavily modified version of osCommerce. I have one very important requirement! You do not develop or change any code in the live store. You will create a copy of the code and put it into /DEV folder on my website. You will then create a copy of the database and point the code in /DEV folder to this new database. All this takes 30 minutes (copy the code, copy atabase, and change 3 files - one .htacces and 2 configs). This will be your development and testing environment. This is where you and I will test and when everything if ok, you will migrate your changes to the live store. Another requirement is that you comment your code with your name, date, and reason for change. Payments: As you see, this project consists of 3 parts. Your bid is for the entire project. You will develop and test 1st part, you tell me when it is ready for me to test, then I test it, you fix errors if I find any, then you migrate this piece to the live store and then I will pay 1/3 of the amount for this part. Then we move to part 2 and so on. I will not do escrow or pay anything in advance. I got burnt too many times. NOW FOR THE PROJECT: Part 1 is a small project to integrate these two modules. I have both CCGV and PWA installed and need to make sure that if a client has Gift voucher(s) in his shopping cart, PWA is disabled, i.e. this client will have to create an account. Same thing with the receiver of the gift voucher. Somebody who has received a gift voucher, can not checkout without creating an account. You will need to test it inside-out. Part 2 is installation , testing, and integration of "Related products" add-on. What I mean by integration is that you will need to make it fit well in the webpage, i.e. adjust the looks to be consistent with the website. Again, these are touch-ups. Part 3 - I need to be able to define descriptions for categories. [login to view URL] - I need same functionality like this. You will need to add an extra field to categories_description table and call it “categories_desc_text” and make it type “longtext”, null by default. Alter the categories php page to include the text from this field if there is text in this field (nothing if there is no text). When you test, make sure I can store html in this field (links, etc). Also alter the admin piece so that I can enter categories descriptions via the admin interface (/admin/[login to view URL]).
