First, consider the purpose of your paper, and evaluate whether it is a secondary vocational school or a higher vocational school. Generally speaking, secondary vocational schools can publish at or above the provincial level, and higher vocational schools need national or even core journals. Graduation thesis, or according to the requirements of the school.
Second, considering the price, the provincial and national core prices are different, but we can't pursue low prices again and again. There are too many fake publications on the Internet. It doesn't matter if you are cheated for hundreds of dollars. The main reason is to delay things, and evaluate the title once a year (if you want to find someone who can pay with Alipay).
Third, the question of time. After the publication is confirmed, it must be determined whether it can be found by the General Administration of Press and Publication. Then time. Generally, it takes 1 month for a magazine to be finalized and published, and it may catch up with the peak in March. If the other party promises you everything, I will send you the manuscript today and tomorrow. This is definitely a fake publication.
Fourth, the price is hard to say. There are too many kinds of magazines, and the prices are judged according to the provincial and national levels. The words of core journals are very different.
hope this helps
