No problem. Just a note on Services that is probably important to you. If they do not belong to the current foreground process, they are given quite a low priority rating by the OS, so they will be terminated quite soon if resources get low. Generally for Services that only exist for a small task this will rarely come in to effect but for your long running Services, you are likely going to be effected by this over a period of time.
