Hi there poker,
As you're fairly new to PCF and you're looking to buy skills, I'm guessing that you might be fairly new to Entropia as well. (If you're an experienced player returning to the game though, you may know most of what I'm about to post anyway)
When posting a buying thread here, it's helpful to other members if the items you want are listed in a simple, factual way. Unfortunately, your first post in this thread is pretty ambiguous.
You say you want to chip up to around level 50 in 'hunting/mining' but there are many professions within these fields, and you give no indication on which one(s) interest you.
For example: Some players prefer melee over ranged weapons; others are really into handguns over longer-ranged weapons; and what about mindforce?.
Within each profession there are also many different interlinked skills which can be combined in very many ways to get you to a particular level. Most skills will impact on multiple professions. And, depending on the current price of skills, some combinations will be far more economical than others. None of us can work that out for you at present because only you know what your current skill levels are.
If you haven't already done so, I recommend you spend some time with jdegre's Chipping Optimiser tool:

Read the instructions carefully.
Use it to look at where you are, where you want to get to in terms of specific professions, and a plan for what skills - and the approximate size of skill chip (in TT value) - it will take to get you there.
And that will make it a lot easier for those selling skills to be able to offer you what you need/want, rather than them having to try to guess.
All the best with your chipping in
