"we are using evaluation version of keil which can compile upto 4k bytes only" (my emphasis). The important word there is Evaluation: the purpose of the Evaluation version is to allow you to Evaluate the suitability of the product to your requirements. Presumably, from your question, you are happy that the product is suitable. Therefore, you need to buy it. If you can't afford it, then you need to seek out an alternative that meets all your requirements - including the budget!
