Where can I find my calendar and how can I add my prices?

Many well-known SaaS companies have doubled their prices. I've personally worked with a few that have gone through it. In most cases, your conversion rates stay the same and you see a huge jump in revenue. This is because people tend to under-price themselves. Also, your product improves over time so it provides more value and can support a higher price. But don't raise prices for old customers. Grandfather them in so their plans stay the same price. In the long run, it won't make a difference to your growth since most of them will churn out anyway. If you raise prices on current customers, you'll get a huge backlash. It gets nasty. I'm pretty sure that Zendesk tried it and had to reverse the price increase. I highly recommend raising your price by 100% for a month on new customers. Keep a close eye on your revenue and your conversion rates. If things don't go well, you can easily reverse it and discount everyone that paid for the more expensive plan. Either way, you'll know what your market will actually support.

I don't think there's a best practice, similar to how much you should charge for your B2B SaaS company, cause it really depends on the market size, cost to deliver, and perceived monetary value you're offering via your API. That being said, the way I've baselined any pricing for my products has been to look at 100 companies that share similar customers and pricing model and either look on their website or email their sales team and ask directly. Even if you get 10% response that's enough to get you started.

For me personally, no. However, what you really need is a larger data set. Gumroad just did a post on prices ending in "9": http://blog.gumroad.com/post/64417917582/a-penny-saved-psychological-pricing 37signals started with prices that ended in 9: http://37signals.com/svn/posts/1287-ask-37signals-how-did-you-come-up-with-pricing-for-your-products ... but they later did research and found it didn't matter (for them). The answer for YOU will likely be to test these things for yourself on your SaaS app.

The first thing you need to do is believe you can get those kinds of rates. You question is littered with reasons why you can't - but the first question you need to ask is "Is there anyone doing development living in Brazil getting paid $100+/hour for their work" - the answer is YES. So, the better question to ask is "What are they doing different then me to get those rates?" I know I've paid for remote developers + designers at the $100/hour range, and the thing that justified it was. 1) I had a budget and have paid that kind of rate in the past 2) They're past work, portfolio, online profile, and all interactions with them world spectacular 3) They had passion for their work, almost like craftman. 4) I felt I could trust that they could over deliver on my expectations 5) They were focused on doing one thing great (ex: Mobile Design, iOS Dev, Ruby Dev) - they didn't do it all. 6) Someone I trusted vouched for them. You don't need all of them, maybe 2-3, but those are some of the things that come to mind.

You're not the only one that struggles with this. Pricing can be tricky for any industry really, but in digital marketing especially so because many still don't understand the value in it. When you can sell the value, then you can sell the price. When it comes to setting a price for anything you can look at it one of two ways, you are either selling value or you are selling your time. When you sell value you have to be at a price that the buyer agrees on the cost of the value being received. If you're selling your time, then you need to determine how much you need for that time and hope the buyer agrees that's what it's worth. With that, you can provide a quote or you can estimate a total cost based on the number of hours you think the job will take. The downside to a quote is that there is often scope creep, that is the client requesting things that you never really intended to be part of the project, or them expecting a certain result and suggesting you have to do whatever it takes to get that result. This is especially important in web marketing because because there is always something more to do to. Many people shy away from hourly work because they don't want to be "nickel and dimed" on every little thing and for the project to end up costing much more than they anticipated. I have found a mixture of the two to work. Provide an estimate based on a certain number of hours per month. Outline what that estimate includes but be flexible if you need to do things that were never included in that estimate. Just make sure the client knows that you stop at whatever hours you agree too each month. Any solution will have issues. You just need to find the one that works best for you and your clients.
