Blacklist and Whitelist Number Filteration

We are currently carrying VOIP traffic in wholesale telecommunication business. We would like to eliminate some calls via white list and black list. White list will have passive number which I will upload it, black list will have some elimination rules such as "if calls start with 00xxx prefix, or contain, or end with. Finally, this traffic will be live traffic therefore this filter may have a capacity for doing more than 1000 process simultaneously. The calls already go through Softswitch. Let’s say simple, asterisk will listen for incoming calls, then apply the rules created to the calls then route the calls to my Softswitch. If ANI or CLD could not pass thru on white or blacklist, that related call will reject with 503 sip code. What I did is I have molded one PBX blacklist extension such that all numbers added there are used as the whitelist. So I have a panel from PBX to upload your whitelist numbers. When uploading a bulk list through CSV, the first column will be number/callerid while 2nd column will be description. I want only serious bidders who have that required knowledge to make this happen. I have also prepared a flowchart which is also attached for better understanding. My budget is 150$ to 160$ max.
