My fee is a flat rate of $50 for a standard upgrade to 1.2. If you want the style to be made responsive, the fee is a flat rate of $75. The fee includes making certain your style performs correctly in every area of 1.2 (including the Resource Manager) and also includes upgrading any custom sprite images you may need, as well as customizing the new editor to match your design. All of my work is 110% satisfaction guaranteed.
Feel free to drop me a message via the contact form at my site (preferred method for faster response) or drop me a PC here and I'll get back to you directly.
