re: entry prices - this is going to vary wildly depending on where you are and what you're able to offer. My best advice would be to do lots of research to find similar providers and see how yours stacks up to theirs.
There are also various marketing approaches too, eg the "sell low but sell many" (eg IKEA) or "sell high but sell few" (eg Louis Vuitton haute couture). You'll need to decide where you want to position yourself from a business point of view, particularly as someone entering a competitive market. Bear in mind you can always shift your prices later - but it may not be wise to have huge variations in price. (eg up/down by $10).
