Here's the thing about SEO that most people seem to forget, and then pay heavy penalties for later: they all work on a set of pre-written patterns. Patterns are like ecstasy to programmers. They are something tangible to work with. So, all the spam algorithms pick up on them quite effectively once their programmers are aware of their existence.
Because the masses use all the decent automation software available, all the pre-configured footprints (patterns) are made known nearly instantly when something new is introduced to the community, if not already. So, if you're going into this thinking that buying said softwares you're asking about, or hoping to be mentioned, will solve your problems without putting in a number of hours of work setting it up to not fall into the problems I have mentioned above, then you're screwed already.
Automation exponentially amplifies the problems of ignorance, apathy, and indifference.
I suggest that you invest in services such as Ahrefs and SerpIQ to help you evaluate the link types and quantities that are ranking sites in the top 20 of your niche. Then, devise up an action plan that meets and exceeds the average for all those sites over a lengthy period of time so that you can easily alter it if shits starts hitting the fan.
After you spend money on research, then buy tools you will need. Scrapebox is a staple, simply because it's very easy to clean up link target lists. Xrumer is as well, but never for money URLs or tier 1 links you care about (that could be said about Scrapebox too). Though that rule can be broken if you are very good at hiding footprints, but nearly everyone isn't even if they think they are. Magic Submitter is good for nearly everything else, but like the previous two - requires significant learning and testing to be anything resembling effective with it.
As for landing page creation, learn HTML, Javascript, and PHP or Python, bro. Until you do, you'll be spending insane amounts of money that could be used better elsewhere. You'll also not understand the full ramafications of my above points, either.
