The best xp for runecrafting is defiantly zmi (Zamorakian Mage Institute). To use the ZMI altar you will need 50 rc which shouldn't take too long to get. The ZMI is located is North of the observatory. If you are on lunar spell book and have 71 magic then you can tele to Ourania or tele to Castle Wars and run there. Before you use the altar it is recommended that you take a shield (any will do) and a mystic mud staff if you are choosing to tele. You will also need 20 of any type of rune to access the bank at ZMI every time you use the bank. This alter IS the best runecrafting xp but not the best for gp as you will only profit once level 85. At around level 50-70 you will only get around 20k xp and it will gradually increase as you lvl. At lvl 90+ its possible to get around 50k xp per hour.
TIP- using mouse keys will increase the xp you get per hour.

A lot
It's hard to tell exactly how much you will make from Runecrafting, all we can say is you should make a lot depending on what runes you make.
It's just to the west of varrock.
