Coding Existing Admin, Adding Features and Merchant Account Integration...Shared Websites with One Database in Custom CMS

Website is built, currently is: [login to view URL] and [login to view URL] (both share the same database) What we did was create a new layout and implement the code from [login to view URL] into it. Now it looks like this: [login to view URL] [login to view URL] had been coded previously but has been missing a link to merchant account and automated email system to send to customers, save data to custom cms. Within that same database we also share information from the other website. The scope of the project is to do 1-4 for [login to view URL] and 5 for [login to view URL]: 1. Ensure the coding is 100% as [login to view URL] up to the check out part. Currently it seems like all has transferred over from the website migration but it may have a glitch, (which we have not yet been able to find) so it may be ok. 2. Link up our merchant account: (we use braintree gateway) into our final page so we can check out 3. I would need some minor changes, that may require CSS work to maybe modify the fonts on our homepage buttons, create 2 or three more links below so we can have a privacy policy, returns page (not complicated) 4. clean up current coding by adding fields to members that log into their account. 5. Scope of work attached for [login to view URL] (please we must review it together first so you will do it correct the first time. Please ensure if you are bidding that you review this brief as we will need this all delivered in no more than 5 days. Experienced coders./ developers only.
