Can I use Restrict Content Pro and User Profiles Made Easy together on the same site and will they coordinate (both from Code Canyon)?

Pricing for different tasks that require the same amount of time from you tells the Customer (and your subconscious) that you're working at a 5 on task x, but working at a 9 on task y simply because it costs/earns more. That seems to be a disconnect. Your time is your most precious asset, and I would charge for it whatever you're doing. If you build a site, and they are happy with your dev fee, but feel like you should charge less for SEO, simply let them find another SEO guy. That's their choice, but YOU are worth $xx.xx, no matter what you're doing. Also, in general, take whatever you're charging and add 10% to it. If you're still busy, add another 10%. Let the demand level determine how much work you do, and at what cost.

I've taken a quick look at your site and am happy to talk to you. Take a look at my reviews here on Clarity. Product advice is an area I provide a lot of help to Clarity members about.

Well first off I wouldn't recommend trying to power your client's database with the standard WordPress database instance. They can use WordPress for the website all they like. But with millions of records like that, you really don't want to move those data in with WordPress. For that matter, you're probably gonna want a dedicated database server to answer those questions, if the client doesn't already have one. You might also need to investigate something like Elastic Search, depending on what your search requirements are and what sort of database they are using (pay close attention to whether or not it provides full text search ability). Beyond that, and somewhat obviously, you're also gonna want SSL on the website and to make sure you're up to date on federal and state privacy requirements for data like this, as well as best practices for securely transferring data over the web (port configuration, ssh keys, etc). The privacy concerns would raise a flag for me. If those data have anything personally identifiable in them - which they very probably do - then you're really gonna want to make sure you do your research on security of personally identifiable information. Government specific privacy /security /auditability requirements may also apply, so double check that too.

I second invision for showing quick online prototypes, but for something more versatile, i use AxureRP (www.axure.com) . The ability to build a sketchy wireframe or a pixel perfect app is amazing. I love it. Great for mobile gestures and animations. Go check it out - they offer a free trial. Contact me if you want more info but they have awesome tutorials on the site. I taught myself everything.

There is no clear call to action on the site. What do you want a visitor to do? What's the primary goal, the secondary goal, etc. Additionally there is no value proposition. Yes you have reviews but so what. If I am the ideal customer why should I do x goal? These 2 elements will have the biggest impact on conversion, not color or anything else.
